u = unchanged, x = unknown, - = unimplemented bit, read as â0â, q = value depends on condition.

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.

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).

One or more bits in the INTCONx or PIRx registers will be affected (to cause wake-up).

See Table 5-1 for Reset value for specific conditions.

Bits 6 and 7 of PORTA, LATA and TRISA are enabled depending on the oscillator mode selected. When

not enabled as PORTA pins, they are disabled and read as â0â.
