Recover MCU ATtiny861 Software from opened microcontroller attiny861 after crack it, and then read the firmware out from program and eeprom memory of microprocessor attiny861.
Reset input. A high on this pin for two machine cycles while the oscillator is running resets the devMCUe. This pin drives High for 98 oscillator periods after the Watchdog times out. The DISRTO bit in SFR AUXR (address 8EH) can be used to disable this feature. In the default state of bit DISRTO, the RESET HIGH out feature is enabled.
Address Latch Enable is an output pulse for latching the low byte of the address during accesses to external memory. This pin is also the program pulse input (PROG) during Flash programming.
In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped during each access to external data memory.
If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only during a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the mMCUrocontroller is in external execution mode after Recover P89LPC925FDH MCU hex.
Program Store Enable is the recover strobe to external program memory. When the AT89C55WD is executing code from external program memory, PSEN is activated twMCUe each machine cycle, except that two PSEN activations are skipped during each access to external data memory.
External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset.
EA should be strapped to VCC for internal program executions. This pin also receives the 12V programming enable voltage (VPP) during Flash programming. Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
Output from the inverting oscillator amplifier. A map of the on-chip memory area called the Special Function Register (SFR) space is shown in Table 1 before break microcontroller pic12f629 program.
Note that not all of the addresses are occupied, and unoccupied addresses may not be implemented on the chip. Recover accesses to these addresses will in general return random data, and write accesses will have an indeterminate effect.
User software should not write 1s to these unlisted locations, since they may be used in future products to invoke new features. In that case, the reset or inactive values of the new bits will always be 0.
Timer 2 Registers: Control and status bits are contained in registers T2CON (shown in Table 2) and T2MOD (shown in Table 2) for Timer 2. The register pair (RCAP2H, RCAP2L) are the Capture/Reload registers for Timer 2 in 16-bit capture mode or 16-bit auto-reload mode.
