16.3.3 Stop and Wait Mode Disable Function
The DSC core contains both STOP and WAIT instructions. Both put the CPU to sleep.
The peripheral bus continues to run in wait mode, but in stop mode, only peripherals
whose SDn control is asserted continue to run. Entry into stop or wait mode does not
affect the OCCS configuration and affects only the generation of system and peripheral
clocks from the master clocks from the OCCS. The OCCS may be reconfigured prior to
entering stop or wait, if desired, to reduce master clock frequencies and thus the power
use within the OCCS.
Some applications require the DSC STOP/WAIT instructions to be disabled. Control
fields are provided in the CTRL register to disable wait and/or stop modes. This
procedure can be on either a permanent (until reset) or temporary basis.
16.4 Resets
The SIM supports several sources of reset, as shown in the following table.
