DS41291G-page 225 PIC16F882/883/884/886/887 14.3.2 TIMER0 INTERRUPT An overflow (FFh 00h) in the TMR0 register will set the T0IF (INTCON<2>) bit. The interrupt can be enabled/disabled by setting/clearing T0IE (INTCON<5>) bit. See Section 5.0 “Timer0 Module” for operation of the Timer0 module. 14.3.3 PORTB INTERRUPT An input change on PORTB change sets the RBIF (INTCON<0>) bit. The interrupt can be enabled/disabled by setting/clearing the RBIE (INTCON<3>) bit. Plus, individual pins can be configured through the IOCB register. FIGURE 14-7: INTERRUPT LOGIC Note: If a change on the I/O pin should occur when the read operation is being executed (start of the Q2 cycle), then the RBIF interrupt flag may not get set. See Section 3.4.3 “Interrupt-on-Change” for more information.

Since the system clock is suspended during Sleep, these peripherals will not wake the part from Sleep. See Section 14.6.1 “Wake-up from Sleep”. BCLIE BCLIF ULPWUIF ULPWUIE CCP2IF CCP2IE |
