Hi

The FTM (used for PWM) can be optionally clocked from the MCGFFCLK but not directly from OSCERCLK.

See µTasker MCG Configuration Support

Depending on the configuration of the MCG ,MCGFFCLK may be related to OSCERCLK (or derived from it) but it is highly unlikely that it will be the same frequency.

Regards
