Description
Standby Crystal
Specifies whether the crystal oscillator halts or
oscillates in standby mode.
0: Halts the oscillation of the crystal oscillator in
1: Continues the oscillation of the crystal oscillator
Reserved
These bits are always read as 0. The write value
should always be 0.
Module Stop 2
Specifies halting the clock supply to the timer unit
TMU (an on-chip supporting module). When the
MSTP2 bit is set to 1, the supply of the clock to the
TMU is halted.
0: TMU runs.
1: Clock supply to TMU is halted.
Module Stop 1
Specifies halting the clock supply to the realtime
clock RTC (an on-chip supporting module). When
the MSTP1 bit is set to 1, the supply of the clock to
RTC is halted. When the clock halts, all RTC
registers become inaccessible, but the counter
keeps running.
0: RTC runs.
1: Clock supply to RTC is halted.
Module Stop 0
Specifies halting the clock supply to the serial
communication interface SCI (an on-chip
supporting module). When the MSTP0 bit is set to
1, the supply of the clock to the SCI is halted.
0: SCI operates.
1: Clock supply to SCI is halted.
