16-bit reload timer
The 16-bit reload timer has the internal clock mode to decrement in synchronization with 3 different internal
clocks and the event count mode to decrement upon detection of an arbitrary edge of the pulse input to the
external pin. Either can be selected. This timer defines when the count value changes from 0000H to FFFFH as
an underflow. The timer therefore causes an underflow when the count reaches [reload register setting + 1].
Either mode can be selected for the count operation from the reload mode which repeats the count by reloading
the count setting value at the underflow occurrence or the one-shot mode which stops the count at the underflow
occurrence. The interrupt can be generated at the counter underflow occurrence so as to correspond to the DTC.
