Bits 7:0 – ADDR[7:0]: Address

Address

This register contains the address of the external client device. When this bit field is written, the TWI will issue a Start condition, and the shift register performs a byte transmit operation on the bus depending on the bus state.

This register can be read at any time without interfering with the ongoing bus activity since read access does not trigger the host logic to perform any bus protocol-related operations.

The host control logic uses bit 0 of this register as the R/W direction bit.
