6.5.2 SIM Counter During Stop Mode Recovery
The SIM counter also is used for stop mode recovery. The STOP
instruction clears the SIM counter. After an interrupt or reset, the SIM
senses the state of the short stop recovery bit, SSREC, in the
configuration register. If the SSREC bit is a logic 1, then the stop
recovery is reduced from the normal delay of 4096 CGMXCLK cycles
down to 32 CGMXCLK cycles.
6.5.3 SIM Counter and Reset States
The SIM counter is free-running after all reset states. See 6.4.1 Active
Resets from Internal Sources for counter control and internal reset
recovery sequences.
6.6 Program Exception Control
Normal, sequential program execution can be changed in two ways:
1. Interrupts
a. Maskable hardware CPU interrupts
b. Non-maskable software interrupt instruction (SWI)
2. Reset
