Overview of Prescaler

The prescaler generates the count clock source for various peripheral resources from
the machine clock (MCLK) and the count clock output from the time-base timer.
Prescaler
The prescaler generates the count clock source for various peripheral resources from the machine clock
(MCLK) that drives the CPU and the count clock (2
The count clock source is a clock frequency-divided by the prescaler or a buffered clock, used by the
peripheral resources listed below. Note that the prescaler has no control register and operates continuously
driven by the machine clock (MCLK) and the count clock (2
