Shaded cells indicate conditions do not apply for the designated device.
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).
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.
See Table 3-2 for Reset value for specific condition.
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’.
Bit 6 of PORTA, LATA and TRISA are not available on all devices. When unimplemented, they are read ‘0’.
If MCLR function is disabled, PORTG<5> is a read-only bit.
Enabled only in Microcontroller mode for PIC18F8525/8621 devices.
The MEMCON register is unimplemented and reads all ‘0’s when the device is in Microcontroller mode.
