Program counter (PC)

The program counter is a 16-bit counter consisting of two 8-bit registers PCH and PCL. It is used to indicate the address of the next instruction to be executed.

Processor status register (PS)

The processor status register is an 8-bit register consisting of flags which indicate the status of the processor after an arithmetic operation. Branch operations can be performed by testing the Carry (C) flag, Zero (Z) flag, Overflow (V) flag, or the Negative (N) flag. In decimal mode, the Z, V, N flags are not valid.

After reset, the Interrupt disable (I) flag is set to “1”, but all other flags are undefined. Since the Index X mode (T) and Decimal mode (D) flags directly affect arithmetic operations, they should be initialized in the beginning of a program.

  • Carry flag (C)

The C flag contains a carry or borrow generated by the arithmetic logic unit (ALU) immediately after an arithmetic operation. It can also be changed by a shift or rotate instruction.

El desbloqueo de la memoria flash del microcontrolador seguro RENESAS M38039FFLHP se ejecutará a partir de 3 pasos principales: el primero es la inspección y el análisis eléctricos, el segundo es la aplicación de fallo de energía para la restauración del sistema de resistencia a manipulaciones del MCU M38039FFLHP protector, el tercero es la lectura del archivo binario del programa del microprocesador cifrado M38039FFLHP;

  • Zero flag (Z)

The Z flag is set if the result of an immediate arithmetic operation or a data transfer is “0”, and cleared if the result is anything other than “0”.

  • Interrupt disable flag (I)

The I flag disables all interrupts except for the interrupt generated by the BRK instruction. Interrupts are disabled when the I flag is “1”.

Lo sblocco della memoria flash del microcontroller protetto RENESAS M38039FFLHP verrà eseguito in 3 passaggi principali, il primo è l'ispezione e l'analisi elettrica, il secondo è l'applicazione di problemi di alimentazione per il ripristino del sistema di protezione antimanomissione MCU M38039FFLHP, il terzo è la lettura del file binario del programma crittografato del microprocessore M38039FFLHP;

When an interrupt occurs, this flag is automatically set to “1” to prevent other interrupts from interfering until the current interrupt  is serviced.
