Module Stop Mode
Module stop mode can be set for individual on-chip peripheral modules.
When the corresponding MSTP bit in MSTPCR or EXMSTPCR is set to 1, module operation
stops at the end of the bus cycle and a transition is made to module stop mode. The CPU continues
operating independently.
When the corresponding MSTP bit is cleared to 0, module stop mode is cleared and the module
starts operating at the end of the bus cycle. In module stop mode, the internal states of modules
other than the PWM, PWMX, SCI, and IIC3 are retained.
After reset clearance, all modules are in module stop mode.
The module registers which are set in module stop mode cannot be read or written to.
