Break Microcontroller Samsung S3F9454 locked memory and extract MCU S3F9454 software from flash memory, the program will be cloned from Microprocessor through universal programmer, an adaptive socket will be required for the whole process;

The SAM88RCRI instruction set is designed to support the large register file. It includes a full complement of 8-bit arithmetic and logic operations. There are 41 instructions. No special I/O instructions are necessary because I/O control and data registers are mapped directly into the register file. Flexible instructions for bit addressing, rotate, and shift operations complete the powerful data manipulation capabilities of the SAM88RCRI instruction set when break Microcontroller.

REGISTER ADDRESSING

To access an individual register, an 8-bit address in the range 0-255 or the 4-bit address of a working register is specified. Paired registers can be used to construct 13-bit program memory or data memory addresses. For detailed information about register addressing, please refer to Chapter 2, “Address Spaces”.

ADDRESSING MODES

There are six addressing modes: Register (R), Indirect Register (IR), Indexed (X), Direct (DA), Relative (RA), and Immediate (IM). For detailed descriptions of these addressing modes, please refer to Chapter 3, “Addressing Modes”.

FLAG DESCRIPTIONS

33Overflow Flag (FLAGS.4, V)

The V flag is set to “1″ when the result of a two’s-complement operation is greater than + 127 or less than – 128.

It is also cleared to “0″ following logic operations.

Sign Flag (FLAGS.5, S)

Following arithmetic, logic, rotate, or shift operations, the sign bit identifies the state of the MSB of the result. A logic zero indicates a positive number and a logic one indicates a negative number.

Zero Flag (FLAGS.6, Z)

For arithmetic and logic operations, the Z flag is set to “1″ if the result of the operation is zero. For operations that test register bits, and for shift and rotate operations, the Z flag is set to “1″ if the result is logic zero.

Carry Flag (FLAGS.7, C)

The C flag is set to “1″ if the result from an arithmetic operation generates a carry-out from or a borrow to the bit 7 position (MSB). After rotate and shift operations, it contains the last value shifted out of the specified register. Program instructions can set, clear, or complement the carry flag.
