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
3: When the wake-up is due to an interrupt and the GIEL or GIEH bit is set, the TOSU, TOSH and TOSL are
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
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’.
