Name:
Access:
Address:
• DELAY[15:0]: PWM Delay on Channel X
Number of counter cycles during which the output is inactive.
Note:
Change of this value is immediately taken into account. This may cause a bad delay on the current pulse.
21.7
Name:
Access:
Address:
• PULSE[15:0]: Pulse Width on Channel X
Number of counter cycles during which the output is active.
Note:
Change of this value is immediately taken into account. This may cause a bad delay on the current pulse.
