counting until the next start trigger is detected.
operation using INTTMn of the master channel as a start trigger, and loads the value of TDRm. TCRm counts down
from the value of TDRm it has loaded, in synchronization with the count value. When the count value = 0000H, it
outputs INTTMm and stops counting until the next start trigger (INTTMn of the master channel) is detected. The
output level of TOm becomes active one count clock after generation of INTTMn from the master channel, and
inactive when TCRm = 0000H.
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 pulse delay time. TCRn of the master channel
The slave channel operates in the one-count mode and counts the pulse width. TCRm of the slave channel starts
Instead of using the TIn pin input, a one-shot pulse can also be output using the software operation (TSn = 1) as a
Caution The timing of loading of TDRn of the master channel is different from that of TDRm of the slave
Remark
Delay time = {Set value of TDRn (master) + 2} × Count clock period
Pulse width = {Set value of TDRm (slave)} × Count clock period
channel. If TDRn and TDRm are rewritten during operation, therefore, an illegal waveform is
output. Rewrite the TDRn register after INTTMn is generated and the TDRm register after INTTMm
is generated.
