System Integration Module (SIM)

7.6.2 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 or break also causes an exit from stop mode.
The SIM disables the clock generator module output (CGMOUT) in stop mode, stopping the CPU and
peripherals. Stop recovery time is selectable using the SSREC bit in the configuration register 1
(CONFIG1). If SSREC is set, stop recovery is reduced from the normal delay of 4096 ICLK cycles down
to 32. This is ideal for applications using canned oscillators that do not require long start-up times from
stop mode.

EXITSTOPWAIT
NOTE: EXITSTOPWAIT = RST pin OR CPU interrupt OR break interrupt
External crystal applications should use the full stop recovery time by
clearing the SSREC bit.
