Legend: u = unchanged, x = unknown, -= unimplemented bit, read as ’0’, q = value depends on condition

Note 1: One or more bits in the INTCONx or PIRx registers will be affected (to cause wake-up).

2: 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).

3: 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 hard-

ware stack.

4: See Table 3-2 for reset value for specific condition.

5: Bit 6 of PORTA, LATA, and TRISA are enabled in ECIO and RCIO oscillator modes only. In all other

oscillator modes, they are disabled and read ’0’.

6: The long write enable is only reset on a POR or MCLR reset.

7: Bit 6 of PORTA, LATA and TRISA are not available on all devices. When unimplemented, they are read ’0’.
