Data memory is composed of registers or bytes of RAM. Therefore, data memory for a device is specified by its register file. The register file is divided into two functional groups: Special Function Registers (SFR) and General Purpose Registers (GPR) after Recover PIC MCU.

The Special Function Registers include the TMR0 register, the Program Counter (PCL), the STATUS register, the I/O registers (ports) and the File Select Register (FSR). In addition, Special Function Registers are used to control the I/O port configuration and prescaler options when Recover PIC MCU.

The General Purpose Registers are used for data and control information under command of the instructions. For the PIC12F510, the register file is composed of 10 Special Function Registers, 6 General Purpose if Recover PIC MCU.

Registers and 32 General Purpose Registers accessed For the PIC16F506, the register file is composed of 13 Special Function Registers, 3 General Purpose Registers and 64 General Purpose Registers accessed for Recover PIC MCU.

The Special Function Registers (SFRs) are registers used by the CPU and peripheral functions to control the operation of the device (see Table 4-1).

The Special Function Registers can be classified into two sets. The Special Function Registers associated with the “core” functions are described in this section for the purpose of Recover PIC MCU.

Those related to the operation of the peripheral features are described in the section for each peripheral feature.

This register contains the arithmetic status of the ALU, the Reset status and the page preselect bit.

The STATUS register can be the destination for any instruction, as with any other register. If the STATUS register is the destination for an instruction that affects the Z, DC or C bits, then the write to these three bits is disabled. These bits are set or cleared according to the device logic. Furthermore, the TO and PD bits are not writable. Therefore, the result of an instruction with the STATUS register as destination may be different than intended.

For example, CLRF STATUS, will clear the upper three bits and set the Z bit. This leaves the STATUS register

as 000u u1uu (where u = unchanged).

Therefore, it is recommended that only BCF, BSF and MOVWF instructions be used to alter the STATUS register. These instructions do not affect the Z, DC or C bits from the STATUS register. For other instructions which do affect Status bits.

We can Recover Mcu ATTINY4313A Code, please view the Mcu ATTINY4313A features for your reference :

The ATtiny2313A/4313 provides the following features: 2/4K bytes of In-System Programmable Flash, 128/256 bytes EEPROM, 128/256 bytes SRAM, 18 general purpose I/O lines, 32 general purpose working registers, a single-wire Interface for On-mcu Debugging, two flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, Universal Serial Interface with Start Condition Detector, a programmable Watchdog Timer with internal Oscillator, and three software selectable power saving modes when Recover Mcu.

The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other mcu functions until the next interrupt or hardware reset if Recover Mcu.

In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low-power consumption. The device is manufactured using Atmel’s high density non-volatile memory technology before Recover Mcu.

The On-mcu ISP Flash allows the program memory to be reprogrammed In-System through an SPI serial interface, or by a conventional non-volatile memory programmer before Recover Mcu.

By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic mcu, the Atmel ATtiny2313A/4313 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications after Recover Mcu.

The ATtiny2313A/4313 AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits if Recover Mcu.

This documentation contains simple code examples that briefly show how to use various parts of the device. These code examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent before Recover Mcu.

Please confirm with the C compiler documentation for more details.

For I/O Registers located in the extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions must be replaced with instructions that allow access to extended I/O. Typically, this means “LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR” after Recover Mcu.

Note that not all AVR devices include an extended I/O map.

For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written.

I/O Registers within the address range 0x00 – 0x1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions.

Some of the status flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI instructions will only operate on the specified bit, and can therefore be used on registers containing such status flags when Recover Mcu.

The CBI and SBI instructions work with registers 0x00 to 0x1F only;

When using the I/O specific commands IN and OUT, the I/O addresses 0x00 – 0x3F must be used. When addressing I/O

Registers as data space using LD and ST instructions, 0x20 must be added to these addresses after Recover Mcu.

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port D is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port D output buffers have symmetrical drive characteristics with both high sink and source capability.

Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running and provided that the reset pin has not been disabled. The minimum pulse length is given in Table 21-3 on page 198. Shorter pulses are not guaranteed to generate a reset. The Reset Input is an alternate function for PA2 and dW. The reset pin can also be used as a (weak) I/O pin. The ATtiny2313A/4313 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny2313A/4313 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed when Recover MCU.

The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers before Recover MCU.

We can recover MCU PIC16F72A Firmware, please view the microchip mcu features for your reference:

This document contains device specific information for the operation of the PIC16F72 device. Additional information may be found in the PIC™ Mid-Range MCU Reference Manual (DS33023), which may be downloaded from the Microchip website. The Reference Manual should be considered a complementary document to this data sheet, and is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules if recover mcu.

The PIC16F72 belongs to the Mid-Range family of the PIC devices.  The program memory contains 2K words, which translate to 2048 instructions, since each 14-bit program memory word is the same width as each device instruction. The data memory (RAM) contains 128 bytes after recover mcu.

There are 22 I/O pins that are user configurable on a pin-to-pin basis. Some pins are multiplexed with other device functions. These functions include:

· External interrupt

· Change on PORTB interrupt

· Timer0 clock input

· Timer1 clock/oscillator

· Capture/Compare/PWM

· A/D converter

· SPI/I2C

Table 1-1 details the pinout of the device with descriptions and details for each pin when recover mcu.

There are two memory blocks in the PIC16F72 device. These are the program memory and the data memory. Each block has separate buses so that concurrent access can occur. Program memory and data memory are explained in this section. Program memory can be read internally by the user code (see Section 7.0).

The data memory can further be broken down into the general purpose RAM and the Special Function Registers (SFRs). The operation of the SFRs that control the “core” are described here. The SFRs used to control the peripheral modules are described in the section discussing each individual peripheral module for the purpose of recover mcu.

Additional information on device memory may be found in the PIC™ Mid-Range Reference Manual, (DS33023).

PIC16F72 devices have a 13-bit program counter capable of addressing a 8K x 14 program memory space.

The address range for this program memory is 0000h  07FFh. Accessing a location above the physically implemented address will cause a wraparound.

The RESET Vector is at 0000h and the Interrupt Vector is at 0004h for recover mcu.

The Data Memory is partitioned into multiple banks that contain the General Purpose Registers and the Special Function Registers. Bits RP1 (STATUS<6>) and RP0 (STATUS<5>) are the bank select bits.
