Module Standby Function

Setting the MSTP6–MSTP0, CSTP1, and CSTP0 bits in the standby control register to 1 enables

the clock supply to the corresponding on-chip peripheral modules to be halted. Use of this

function allows power consumption in sleep mode to be further reduced.

In the module standby state, the on-chip peripheral module external pins retain their states prior to

halting of the modules, and most registers retain their states prior to halting of the modules.
