operating upon start trigger detection and TCR0n loads the value of TDR0n. TCR0n counts down from the value of
TDR0n it has loaded, in synchronization with the count clock. When TCR0n = 0000H, it outputs INTTM0n and stops

operation using INTTM0n of the master channel as a start trigger, and loads the TDR0m value. TCR0m counts down
from the value of TDR0m it has loaded, in synchronization with the count value. When TCR0m = 0000H, it outputs
INTTM0m and stops counting until the next start trigger (INTTM0n of the master channel) is detected. The output

Caution The timing of loading of TDR0n of the master channel is different from that of TDR0m of the slave
By using two channels as a set, a one-shot pulse having any delay pulse width can be generated from the signal
The delay time and pulse width can be calculated by the following expressions.
The Master channel operates in the one-count mode and counts the delays. TCR0n of the master channel starts
The slave channel operates in the one-count mode and counts the pulse width. TCR0m of the slave channel starts
Instead of using the TI0n pin input, a one-shot pulse can also be output using the software operation (TS0n = 1) as
Remark
Delay time = {Set value of TDR0n (master) + 2} × Count clock period
Pulse width = {Set value of TDR0m (slave)} × Count clock period

output. Rewrite the TDR0n after INTTM0n is generated and the TDR0m after INTTM0m is generated.
