CRCn
TMn operates as an interval timer when 16-bit timer mode control register n (TMCn) and capture/compare control
In this case, TMn repeatedly generates an interrupt at the time interval specified by the count value set in advance
When the count value of TMn matches the set value of CRn0, the value of TMn is cleared to 0, and the timer
The count clock of the 16-bit timer/event counter can be selected by bits 0 and 1 (PRMn0 and PRMn1) of prescaler
