45.6.7 TWIHS Comparison Function on Received Character

The comparison function differs if asynchronous partial wake-up is enabled or not.

If asynchronous partial wake-up is disabled (see the section “Power Management Controller (PMC)”), the TWIHS can extend the address matching on up to three client addresses. The SADR1EN, SADR2EN and SADR3EN bits in TWIHS_SMR enable address matching on additional addresses which can be configured through SADR1, SADR2 and SADR3 fields in TWIHS_SWMR. The DATAMEN bit in TWIHS_SMR has no effect.

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