I²C Interface

11.1

I²C Address and Protocol

The STV82x7 I²C interface works in Slave mode and is fully compliant with I²C standards in Fast

mode (maximum frequency of 400 kHz). Two pairs of I²C chip addresses are used to connect two

STV82x7 chips to the same I²C serial bus. The device address pairs are defined by the polarity of

the ADR_SEL pin and are listed in the following table:

Protocol Description

● Write Protocol

● Read Protocol

● W = Write address,

● R = Read address,

● A = Acknowledge,

● N = No acknowledge,

● Sub-address is the register address pointer; this value auto-increments for both write and read.
