9.6 Module Standby Function
9.6.1 Transition to 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.
