Stop and Wait Mode Disable Function

Preliminary
All peripherals, except the COP/watchdog timer, run off the IPBus clock frequency, which is the same as
the main processor frequency in this architecture. The maximum frequency of operation is
SYS_CLK = 60MHz.
6.8 Stop and Wait Mode Disable Function
Figure 6-16 Stop Disable Circuit
Stop
System clocks continue to be generated in
the SIM, but most are gated prior to
reaching memory, core and peripherals.
The only possible recoveries from Stop mode are:
1. CAN traffic (1st message will be lost)
2. Non-clocked interrupts
3. COP reset
4. External reset
5. Power-on reset
