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.
Figure 15-17
15.6.2 Stop Mode
In stop mode, the SIM counter is reset and the system clocks are disabled. An interrupt request from a
module can cause an exit from stop mode. Stacking for interrupts begins after the selected stop recovery
time has elapsed. Reset also causes an exit from stop mode.
The SIM disables the clock generator module outputs (CGMOUT and CGMXCLK) in stop mode, stopping
the CPU and peripherals. Stop recovery time is selectable using the SSREC bit in CONFIG1. If SSREC
is set, stop recovery is reduced from the normal delay of 4096 CGMXCLK cycles down to 32. This is ideal
for applications using canned oscillators that do not require long startup times from stop mode.

and
EXITSTOPWAIT
Note: EXITSTOPWAIT = RST pin, CPU interrupt, or break interrupt
External crystal applications should use the full stop recovery time by
clearing the SSREC bit unless OSCENINSTOP bit is set in CONFIG2.
