14.6.1 Wait Mode
In wait mode, the CPU clocks are inactive while the peripheral clocks continue to run.
the timing for wait mode entry.
A module that is active during wait mode can wakeup the CPU with an interrupt if the interrupt is enabled.
Stacking for the interrupt begins one cycle after the WAIT instruction during which the interrupt occurred.
In wait mode, the CPU clocks are inactive. Refer to the wait mode subsection of each module to see if the
module is active or inactive in wait mode. Some modules can be programmed to be active in wait mode.
Wait mode also can be exited by a reset or break. A break interrupt during wait mode sets the SIM break
stop/wait bit, SBSW, in the SIM break status register (BSR). If the COP disable bit, COPD, in the
CONFIG1 register is 0, then the computer operating properly module (COP) is enabled and remains
active in wait mode.
