8.7.2 Operation as external event counter
(external event) is detected in the TImn 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.

Remark m: Unit number (m = 0, 1), n: Channel number (n = 0 to 7)
The timer array unit can be used as an external event counter that counts the number of times the valid input edge
Timer/counter register mn (TCRmn) operates as a down counter in the event counter mode.
The TCRmn register loads the value of timer data register mn (TDRmn) by setting any channel start trigger bit (TSmn)
The TCRmn register counts down each time the valid input edge of the TImn pin has been detected. When TCRmn =
After that, the above operation is repeated.
An irregular waveform that depends on external events is output from the TOmn pin. Stop the output by setting the
The TDRmn register can be rewritten at any time. The new value of the TDRmn register becomes valid during the next
