9.3.9.7 TWI Comparison Function on Received Character

The comparison function differs if the asynchronous partial wakeup is enabled or not.

If asynchronous partial wakeup is disabled, the TWI has the capability to extend the address matching on up to three client addresses. The FLEX_TWI_SMR.SADR1EN/SADR2EN/SADR3EN bits enable address matching on additional addresses which can be configured through the FLEX_TWI_SWMR.SADR1/SADR2/SADR3 fields. The DATAMEN bit has no effect.

The SVACC bit is set when there is a comparison match with the received client address.
