Data Update Timing (Duty Ratio) - Panasonic FP7 User Manual

Pulse Output / PWM Output Function

9.1.6 Data Update Timing (Duty Ratio)

The following three modes are provided as the timing of changing the data of duty ratio at the
time of PWM output.
 Updating data when PLS start signal rises
In this mode, the data update is performed with the data when a PLS start signal turns on.
The frequency value changed at this timing will be reflected when the outputting pulse falls
next time.

(Y11C)
PWM0 Duty
(UM168-UM169)
 Updating data when comparison output is performed
In this mode, the data update is performed with the data when the counter elapsed value
matches the comparison value. The frequency value changed at this timing will be reflected
when the outputting pulse falls next time.
