SERIAL INTERFACE CONFIGURATION REGISTERS
The serial interface configuration registers can be read and written using the I2C serial control interface, Pin I2C_SDA, and Pin I2C_SCL.
The least significant bits of the AD8191A I2C part address are set by tying Pin I2C_ADDR2, Pin I2C_ADDR1, and Pin I2C_ADDR0 to
3.3 V (Logic 1) or 0 V (Logic 0). As soon as the serial control interface is used, the parallel control interface is disabled until the AD8191A
is reset, as described in the Serial Control Interface section.
