5.7.4.7
5.7.4.8
The following procedure is recommended for starting a PWM drive.
Method 1:
Set 16-bit down counter (CNR) as 0, and monitor PDR (current value of 16-bit down-counter).
When PDR reaches to 0, disable PWM-Timer (CHxEN in PCR). (Recommended)
Method 2:
Set 16-bit down counter (CNR) as 0. When interrupt request happened, disable PWM-Timer
(CHxEN in PCR). (Recommended)
Method 3:
Disable PWM-Timer directly ((CHxEN in PCR). (Not recommended)
The reason why method 3 is not recommended is that disable CHxEN will immediately stop PWM
output signal and lead to change the duty of the PWM output, this may cause damage to the
control circuit of motor
