Read Chip PIC16LF819 Code from its memory include flash and eeprom, the status of Microcontroller PIC16LF819 can be reset to unencrypted one through the MCU cracking technique;
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 when extract mcu atmega8p code.
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) before extract ic atmega162p code.
The lower example in the figure shows how the PC is loaded during aCALL orGOTO instruction (PCLATH<4:3> → PCH). PIC16F7X devices are capable of addressing a continuous 8K word block of program memory.
TheCALL and GOTO instructions provide only 11 bits of address to allow branching within any 2K program memory page. When doing a CALL or GOTO instruction, the upper 2 bits of the address are provided by PCLATH<4:3>.
When doing a CALL or GOTO instruction, the user must ensure that the page select bits are programmed so that the desired program memory page is addressed. If a return from a CALL instruction (or interrupt) is executed, the entire 13-bit PC is popped off the stack.
Therefore, manipulation of the PCLATH<4:3> bits are not required for the RETURN instructions (which POPs the address from the stack). Example 2-1 shows the calling of a subroutine in page 1 of the program memory before Read mcu atmega162l code.
This example assumes that PCLATH is saved and restored by the Interrupt Service Routine (if interrupts are used).
