Shaded cells indicate conditions do not apply for the designated device.
When the wake-up is due to an interrupt and the GIEL or GIEH bit is set, the TOSU, TOSH and TOSL are
updated with the current value of the PC. The STKPTR is modified to point to the next location in the
hardware stack.
One or more bits in the INTCONx or PIRx registers will be affected (to cause wake-up).
When the wake-up is due to an interrupt and the GIEL or GIEH bit is set, the PC is loaded with the
interrupt vector (0008h or 0018h).
See Table 4-3 for Reset value for specific condition.
PORTA<6>, LATA<6> and TRISA<6> are enabled depending on the oscillator mode selected. When not
enabled as PORTA pins, they are disabled and read ‘0’.
