Bit 3—Module Stop 3 (MSTP3): Specifies stopping of the clock supply to serial communication
interface channel 2 (SCIF) among the on-chip peripheral modules. The clock supply to the SCIF is
stopped when the MSTP3 bit is set to 1.
Bit 3: MSTP3

Bit 2—Module Stop 2 (MSTP2): Specifies stopping of the clock supply to the timer unit (TMU)
among the on-chip peripheral modules. The clock supply to the TMU is stopped when the MSTP2
bit is set to 1.
Bit 2: MSTP2
0
1
Bit 1—Module Stop 1 (MSTP1): Specifies stopping of the clock supply to the realtime clock
(RTC) among the on-chip peripheral modules. The clock supply to the RTC is stopped when the
MSTP1 bit is set to 1. When the clock supply is stopped, RTC registers cannot be accessed but the
counters continue to operate.
Bit 1: MSTP1

Bit 0—Module Stop 0 (MSTP0): Specifies stopping of the clock supply to serial communication
interface channel 1 (SCI) among the on-chip peripheral modules. The clock supply to the SCI is
stopped when the MSTP0 bit is set to 1.
Bit 0: MSTP0
