Prescalers
The MCU has the following prescaler S.
The prescaler operating conditions are listed in table 22, and the prescaler output supply is shown in figure
29. The timers A, C, D input clocks except external events and the serial transmit clock except the external
clock are selected from the prescaler outputs, depending on corresponding mode registers.
Prescaler Operation
Prescaler S:
11-bit counter that inputs a system clock signal. After being reset to $000 by MCU reset,
prescaler S divides the system clock. Prescaler S keeps counting, except at MCU reset.
