7.8.2 Operation as one-shot pulse output function
input to the TImn pin.
operating upon start trigger detection and TCRmn loads the value of TDRmn. TCRmn counts down from the value of
TDRmn it has loaded, in synchronization with the count clock. When TCRmn = 0000H, it outputs INTTMmn and stops
counting until the next start trigger is detected.
operation using INTTMmn of the master channel as a start trigger, and loads the TDRmp value. TCRmp counts down
from the value of TDRmp it has loaded, in synchronization with the count value. When TCRmp = 0000H, it outputs
INTTMmp and stops counting until the next start trigger (INTTMmn of the master channel) is detected. The output
level of TOmp becomes active one count clock after generation of INTTMmn from the master channel, and inactive

as a start trigger.

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. TCRmn of the master channel starts
The slave channel operates in the one-count mode and counts the pulse width. TCRmp of the slave channel starts
Instead of using the TImn pin input, a one-shot pulse can also be output using the software operation (TSmn = 1)
Caution The timing of loading of TDRmn of the master channel is different from that of TDRmp of the slave
Remark
Delay time = {Set value of TDRmn (master) + 2} × Count clock period
Pulse width = {Set value of TDRmp (slave)} × Count clock period
channel. If TDRmn and TDRmp are rewritten during operation, therefore, an illegal waveform is
output. Rewrite the TDRmn after INTTMmn is generated and the TDRmp after INTTMmp is
generated.
