Updating SCTimer match register without stopping the timer

[awseiger]

I am implementing a multi-output PWM system, and I need to be able to update the PWM duty cycle of a single channel without disturbing other channels.

However, the SDK driver for the SCTimer stops the timer while changing the register match values. Commenting out the lines that are starting/stopping the SCTimer results in a hard fault.

Am I correct that there is no way to update the match value of an SCTimer event while the timer is running?

Thanks,

Alex

Thank you for the confirmation! The SCTimer is very different from the timers I'm used to, so I want to make sure I understand the limitations.
