the operation, so that a waveform with varying duty cycles is output continuously on external pin
TO6.
10.3.11 One-Shot Pulse Function Pulse Output Timing
There is a maximum delay of one DCNT input clock count clock cycle between setting of the
down-count start flag (DST) and the start of the DCNT down-count. One-shot pulse output also
varies by a delay of one CK state, but there is no error in the one-shot pulse output pulse width.
Figure 10.23 shows an example with a pulse width setting of H'0005.
