6.7.2 Operation as external event counter
(external event) is detected in the TIpq pin. When a specified count value is reached, the event counter generates an
interrupt. The specified number of counts can be calculated by the following expression.
loads the value of TDRpq again, and outputs INTTMpq.

The timer array unit can be used as an external event counter that counts the number of times the valid input edge
TCRpq operates as a down counter in the event counter mode.
When the channel start trigger bit (TSpq) is set to 1, TCRpq loads the value of TDRpq.
TCRpq counts down each time the valid input edge of the TIpq pin has been detected. When TCRpq = 0000H, TCRpq
After that, the above operation is repeated.
TOpq must not be used because its waveform depends on the external event and irregular.
TDRpq can be rewritten at any time. The new value of TDRpq becomes valid during the next count period.
Remark pq: Unit number + Channel number (only for channels provided with timer I/O pins)
Specified number of counts = Set value of TDRpq + 1
