Figure 70. Block diagram of the 2-wire Serial Bus Interface
The CPU interfaces with the 2-wire Serial Interface via the following five I/O registers: the 2-
wire Serial Bit-rate Register (TWBR), the 2-wire Serial Control Register (TWCR), the 2-wire
Serial Status Register (TWSR), the 2-wire Serial Data Register (TWDR), and the 2-wire Serial
Address Register (TWAR, used in Slave mode).
