Sense Synchronization during Automatic PWM Generation

For performing current sense measurements there is a current sense synchronization signal at the pin ISSY

available. This signal indicates the possible start of

IS measurement. The synchronization signal will be activated

after the time

Measurement delay after channel’s activation. The delay time can be configured via SPI register

CHCRn.SYDEL

. The current sense synchronization signal is only available during the automatic PWM generation,

i.e. the bit PCR.PST is set.

Figure 23 shows the functionality of the current sense synchronization signal.
