5.7.1
Prescaler S is a 13-bit counter using the system clock ( ) as its input clock. The outputs, which are
divided clocks, are used as internal clocks by the on-chip peripheral modules. Prescaler S is
initialized to H'0000 by a reset, and starts counting on exit from the reset state. In standby mode
and subsleep mode, the external clock oscillator stops. Prescaler S also stops and is initialized to
H'0000. It cannot be read from or written to by the CPU.
The outputs from prescaler S are shared by the on-chip peripheral modules. The division ratio can
be set separately for each on-chip peripheral module. In active mode and sleep mode, the clock
input to prescaler S is a system clock with the division ratio specified by bits MA2 to MA0 in
SYSCR2.
5.7.2
Prescaler W is a 5-bit counter using a 32.768-kHz signal divided by 4 as its input clock. The
divided output is used for clock time base operation of the RTC. Prescaler W is initialized to H'00
by a reset, and starts counting on exit from the reset state. Even in standby mode, subactive mode,
or subsleep mode, prescaler W continues functioning.
