System Integration Module (SIM)

16.6.2 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 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 the mask option register
(MOR). 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.
