For performing current sense measurements there is a current sense synchronization signal at the pin ISSY
available. This signal indicates the possible start of
after the time
CHCRn.SYDEL. The current sense synchronization signal is only available during the automatic PWM generation,
i.e. the bit PCR.PST is set.
