Copy Microcontroller PIC16F648A Binary from its flash and eeprom memory, the MCU PIC16F648A will be unlocked to ensure the program can be readout directly from its memory, the process of MCU content recovery will normally take 3 working days;
The STATUS register contains the arithmetic status of the ALU, the RESET status and the bank select bits for data memory.
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 if read ic attiny48a heximal.
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).
It is recommended, therefore, that only BCF, BSF, SWAPF and MOVWF instructions are used to alter the STATUS register, because these instructions do not affect the Z, C, or DC bits from the STATUS register.
For other instructions not affecting any status bits, see the “Instruction Set Summary.” The OPTION_REG register is a readable and writable register, which contains various control bits to configure the TMR0 prescaler/WDT postscaler (single assignable register known also as the prescaler), the External INT Interrupt, TMR0 and the weak pull-ups on PORTB.
The INTCON register is a readable and writable register, which contains various enable and flag bits for the TMR0 register overflow, RB Port change and External RB0/INT pin interrupts if read ic atmega261a program.
The Power Control (PCON) register contains flag bits to allow differentiation between a Power-on Reset (POR), a Brown-out Reset (BOR), a Watchdog Reset (WDT) and an external MCLR Reset.
The program counter (PC) is 13 bits wide. The low byte comes from the PCL register, which is a readable and writable register. The upper bits (PC<12:8>) are not readable, but are indirectly writable through the PCLATH register.
On any RESET, the upper bits of the PC will be cleared. Figure 2-4 shows the two situations for the loading of the PC. The upper example in the figure shows how the PC is loaded on a write to PCL (PCLATH<4:0> → PCH).
The lower example in the figure shows how the PC is loaded during aCALL orGOTO instruction (PCLATH<4:3> → PCH).
