184 / 284 page  PIC16F707/PIC16LF707 DS41418A-page 184 Preliminary 2010 Microchip Technology Inc. 21.1.1 WAKE-UP USING INTERRUPTS When global interrupts are disabled (GIE cleared) and any interrupt source has both its interrupt enable bit and interrupt flag bit set, one of the following will occur: • If the interrupt occurs before the execution of a SLEEP instruction - SLEEP instruction will execute as a NOP. - WDT and WDT prescaler will not be cleared -TO bit of the STATUS register will not be set -PD bit of the STATUS register will not be cleared. • If the interrupt occurs during or after the execu- tion of a SLEEP instruction - SLEEP instruction will be completely exe- cuted - Device will immediately wake-up from Sleep - WDT and WDT prescaler will be cleared -TO bit of the STATUS register will be set -PD bit of the STATUS register will be cleared. Even if the flag bits were checked before executing a SLEEP instruction, it may be possible for flag bits to become set before the SLEEP instruction completes. To determine whether a SLEEP instruction executed, test the PD bit. If the PD bit is set, the SLEEP instruction was executed as a NOP.

This delay applies only to XT, HS or LP Oscillator modes. 4: GIE = 1 assumed. In this case after wake-up, the processor calls the ISR at 0004h. If GIE = 0, execution will continue in-line.
