Address

The Client Address (TWIn.SADDR) register is used by the client address match logic to determine if a host device has addressed the TWI client. If an address packet is received, the Address or Stop Interrupt Flag (APIF) and the Address or Stop (AP) bit in the Client Status (TWIn.SSTATUS) register are set to ‘1’.

The upper seven bits (ADDR[7:1]) of the TWIn.SADDR register represent the main client address.

The TWIn.SADDR register's Least Significant bit (ADDR[0]) is used for recognition of the General Call Address (0x00) of the I2C protocol. This feature is enabled when this bit is set to ‘1’.
