I2C-bus Interface
The I2C-bus interface is compliant with the Standard-mode and Fast-mode I2C-bus specifications. The I2C-bus
interface consists of two lines: serial data (SDA) and serial clock (SCL). In the Standard-mode, the serial clock
and serial data can go up to 100 kbps and in the Fast-mode, the serial clock and serial data can go up to 400
kbps.
The first byte sent by an I2C-bus master contains a start bit (SDA transition from HIGH to LOW when SCL is
HIGH), 7-bit slave address and whether it is a read or write transaction. The next byte is the sub-address that
contains the address of the register to access. The XRA120x responds to each write with an acknowledge
(SDA driven LOW by XRA1201/1201P for one clock cycle when SCL is HIGH). The last byte sent by an I2C-
bus master contains a stop bit (SDA transition from LOW to HIGH when SCL is HIGH). See Figures 3 - 5
below. For complete details, see the I2C-bus specifications.
