8.3.9.7 TWI Comparison Function on Received Character
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.
