9.5 Module Standby Function
9.5.1 Transition to Module Standby Function
Setting the standby control register STBCR, STBCR2, STBCR3, MSTP17, MSTP15 to MSTP13,
MSTP11 to MSTP4, and MSTP 2 to MSTP0 bits to 1 halts the clock supply to the corresponding
on-chip supporting modules. By using this function, the power consumption in normal mode and
sleep mode can be reduced.
In the module standby function, external pins of the on-chip supporting modules are different
depending on the on-chip supporting modules. TMU external pins hold their state prior to the halt.
SCI external pins go to the reset state. With a few exceptions, all registers hold their values.
