Auxiliary interrupts will wake up from Idle mode. They are enabled with EAI (EICON.5).
EWUWDT
Enable Wake Up Watchdog Timer. Wake using watchdog timer interrupt.
bit 2
0 = Don’t wake up on watchdog timer interrupt.
1 = Wake up on watchdog timer interrupt.
EWUEX1
Enable Wake Up External 1. Wake using external interrupt source 1.
bit 1
0 = Don’t wake up on external interrupt source 1.
1 = Wake up on external interrupt source 1.
EWUEX0
Enable Wake Up External 0. Wake using external interrupt source 0.
bit 0
0 = Don’t wake up on external interrupt source 0.
1 = Wake up on external interrupt source 0.

Write:
DIVMOD
DIVIDE MODE
00
Normal mode (default, no divide).
01
Immediate mode: start divide immediately; return to Normal mode on Idle mode wakeup condition or by direct write to SFR.
10
Delay mode: same as Immediate mode, except that the mode changes with the millisecond interrupt (MSINT). If MSINT is
enabled, the divide will start on the next MSINT and return to normal mode on the following MSINT. If MSINT is not
enabled, the divide will start on the next MSINT condition (even if masked) but will not leave the divide mode until the
MSINT counter overflows, which follows a wakeup condition. Can exit by directly writing to SFR.
11
Manual mode: start divide immediately; exit mode only by directly writing to SFR. Same as immediate mode, but cannot
return to Normal mode on Idle mode wakeup condition; only by directly writing to SFR.
