6.7.2 Operation as external event counter
(external event) is detected in the TIn 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.
(TS0) to 1.
loads the value of TDRn again, and outputs INTTMn.
TOEn bit of timer output enable register 0 (TOE0) to 0.
The timer array unit can be used as an external event counter that counts the number of times the valid input edge
TCRn operates as a down counter in the event counter mode.
The TCRn loads the value of TDRn by setting any channel start trigger bit (TSn) of timer channel start register 0
TCRn counts down each time the valid input edge of the TIn pin has been detected. When TCRn = 0000H, TCRn
After that, the above operation is repeated.
An irregular waveform that depends on external events is output from the TO0 pin. Stop the output by setting the
TDRn can be rewritten at any time. The new value of TDRn becomes valid during the next count period.
Specified number of counts = Set value of TDRn + 1
