Prescalers
The MCU has a built-in prescaler labeled as prescaler S (PSS).
The prescalers operating conditions are listed in table 24, and the prescalers output supply is shown in
figure 28. The timers A–C input clocks except external events, 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 the system clock signal. After being reset to $000 by MCU reset,
prescaler S divides the system clock.
