16.1 Overview of 16-Bit Reload Timer

The 16-bit reload timer has two modes. In internal clock mode, countdown is

countdown is performed based on detection of any pulse edge input to the external
pin. Either of these modes can be selected.

For the 16-bit reload timer, an underflow is defined as an event where the count value changes

underflow causes repeated counting by reloading the count set value, or one-shot mode, where
an underflow will stop counting, can be selected. A counter underflow can be used to generate
an interrupt, which supports DTC.
