By using two channels as a set, a one-shot pulse having any delay pulse width can be generated from the signal input
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. Timer/counter register mn (TCRmn) of the
The TCRmn register counts down from the value of the TDRmn register it has loaded, in synchronization with the count
The slave channel operates in the one-count mode and counts the pulse width. The TCRmp register of the slave
Instead of using the TImn pin input, a one-shot pulse can also be output using the software operation (TSmn = 1) as a
Caution The timing of loading of timer data register mn (TDRmn) of the master channel is different from that of

Note
Delay time = {Set value of TDRmn (master) + 2} × Count clock period
Pulse width = {Set value of TDRmp (slave)} × Count clock period
the TDRmp register of the slave channel. If the TDRmn and TDRmp registers are rewritten during
operation, therefore, an illegal waveform is output. Rewrite the TDRmn register after INTTMmn is
generated and the TDRmp register after INTTMmp is generated.

Since there is no function of timer I/O, the channel 1 in the 78K0R/KC3-L (40-pin) can not be used as the
slave channel.
