6.7.2 Operation as external event counter
(external event) is detected in the TI0n 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.
TCR0n loads the value of TDR0n again, and outputs INTTM0n.
The timer array unit can be used as an external event counter that counts the number of times the valid input edge
TCR0n operates as a down counter in the event counter mode.
When the channel start trigger bit (TS0n) is set to 1, TCR0n loads the value of TDR0n.
TCR0n counts down each time the valid input edge of the TI0n pin has been detected. When TCR0n = 0000H,
After that, the above operation is repeated.
TO0n must not be used because its waveform depends on the external event and irregular.
TDR0n can be rewritten at any time. The new value of TDR0n becomes valid during the next count period.
TI0n pin
Specified number of counts = Set value of TDR0n + 1
