The PIC16Cxxx family (5)

• The MCLR pin selects the PIC mode, depending on the voltage value:

• 5V (Vcc): firmware execution

• 0V (GND): PIC reset

• 12V - 14V: firmware programming

• Interrupts detected by the PIC are handled by an interrupt handler located at 0004h (interrupt vector)

• When the PIC is reset, it starts executing the instruction located at 0000h (reset vector)
