Question

need help please!!

Right after an interrupt is triggered in PIC16, the hardware interrupt handler will clear the Global Interrupt Enable (GIE) bit. After the Global Interrupt Enable (GIE) bit is cleared in PIC16, no interrupt flags will be set. When an Interrupt Service Routine (ISR) returns to the main program in PIC16, the corresponding interrupt flag will be cleared by hardware interrupt handler automatically The programmer doesn't need to clear the flag Non-maskable interrupts are affected by the Global Interrupt Enable bit (GIE). PUSH and POP are performed by 'Hardware Interrupt Handler,
