Prescaler
The MCU has one built-in prescaler, S (PSS). This divides the system clock and outputs the divided clock
to the peripheral function modules as shown in figure 25.
Clocks for timers B and C except for external events, and clocks for serial interface except for the external
clock are all selected from the prescaler output by programming each mode register.
Prescaler S is an 11-bit counter which inputs the system clock. After an MCU reset clears the prescaler to
$000, it begins dividing the system clock. Prescaler S stops operating due to either an MCU reset or stop
mode. It cannot be stopped by any other mode.
