      PIC16F688
      11.3
      Interrupts
      The PIC16F688 has multiple sources of interrupt:
      External Interrupt RA2/INT
      TMR0 Overflow Interrupt
      PORTA Change Interrupts
      2 Comparator Interrupts
      A/D Interrupt
      Timer1 Overflow Interrupt
      EEPROM Data Write Interrupt
      Fail-Safe Clock Monitor Interrupt
      EUSART Receive and Transmit interrupts
      The Interrupt Control (INTCON) register and Peripheral
      Interrupt Request 1 (PIR1) register record individual
      interrupt requests in flag bits. The INTCON register
      also has individual and global interrupt enable bits.
      A Global Interrupt Enable bit, GIE bit of the INTCON
      register, enables (if set) all unmasked interrupts, or dis-
      ables (if cleared) all interrupts. Individual interrupts can
      be disabled through their corresponding enable bits in
      the INTCON register and PIE1 register. GIE is cleared
      on Reset.
      The Return from Interrupt instruction, RETFIE, exits
      the interrupt routine, as well as sets the GIE bit, which
      re-enables unmasked interrupts.
      The following interrupt flags are contained in the
      INTCON register:
      INT Pin Interrupt
      PORTA Change Interrupt
      TMR0 Overflow Interrupt
      The peripheral interrupt flags are contained in the
      special register, PIR1. The corresponding interrupt
      enable bit is contained in special register, PIE1.
      The following interrupt flags are contained in the PIR1
      register:
      EEPROM Data Write Interrupt
      A/D Interrupt
      EUSART Receive and Transmit Interrupts
      2 Comparator Interrupts
      Timer1 Overflow Interrupt
      Fail-Safe Clock Monitor Interrupt
      When an interrupt is serviced:
      The GIE is cleared to disable any further interrupt.
      The return address is pushed onto the stack.
      The PC is loaded with 0004h.
      For external interrupt events, such as the INT pin or
      PORTA change interrupt, the interrupt latency will be
      three or four instruction cycles. The exact latency
      depends upon when the interrupt event occurs (see
      Figure 11-8). The latency is the same for one or
      two-cycle instructions. Once in the Interrupt Service
      Routine, the source(s) of the interrupt can be
      determined by polling the interrupt flag bits. The
      interrupt flag bit(s) must be cleared in software before
      re-enabling interrupts to avoid multiple interrupt
      requests.
      For additional information on Timer1, A/D or data
      EEPROM modules, refer to the respective peripheral
      section.
      Note 1: Individual interrupt flag bits are set,
      regardless
      of
      the
      status
      of
      their
      corresponding mask bit or the GIE bit.
      2: When an instruction that clears the GIE
      bit is executed, any interrupts that were
      pending for execution in the next cycle
      are ignored. The interrupts, which were
      ignored, are still pending to be serviced
      when the GIE bit is set again.
