ADV3000
SERIAL INTERFACE CONFIGURATION REGISTERS
The serial interface configuration registers can be read and written using the I
2
C serial control interface, Pin I2C_SDA, and Pin I2C_SCL.
The least significant bit of the ADV3000 I
2
C part address is set by tying 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 ADV3000 is reset as described in the Serial Control
Interface section.
