10. 16-bit reload timer
The 16-bit reload timer provides two functions either one which can be selected, the internal clock the performs
the count down by synchronizing with 3-type internal clocks and the event count mode that performs the count
down by detecting the arbitration. This timer defines an underflow as a transition of the count value from 0000H
to FFFFH. Therefore, when the equation (counted value
= reload register setting value+1) holds, an underflow
occurs. 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 corre-
spond to the DTC.
