Legend: u = unchanged, x = unknown, - = unimplemented read as '0', q = value depends on condition.
Note 1: One or more bits in INTSTA, PIR1, PIR2 will be affected (to cause wake-up).
2: When the wake-up is due to an interrupt and the GLINTD bit is cleared, the PC is loaded with the interrupt
vector.
3: See Table 5-3 for reset value of specific condition.
4: If Brown-out is enabled, else the BOR bit is unknown.
