Step 3. PLS control signal
●
Beside PLS/PWM setting, Enable, start and direction signals are
needed to be controlled by PLS control signal.
Enable signal
→
Enable signal determines valid/stop of pulse output.
ON: Pulse output valid
OFF: Pulse output stop
Start signal
→
Start signal starts up pulse output, or change output frequency.
Frequency can also be changed at the time of comparison
coincidence or data refresh, by
Pulse output setting
configuration.
Start signal is valid only when Enable signal is ON. If not, start signal
is invalid. When both Enable and Start signals are ON, pulse output
is permitted.
Direction signal
→
Direction signal controls the direction of pulse output.
OFF: Forward
ON: Reverse
●
Output allocation for each control signal is shown in the table

Direction signal can be changed even during pulse output,
but timing with pulse output cannot be specified.
Change the signal when pulse is stopped.
