TWO-WIRE INTERFACE [I
2
C, MODE (PIN 28) = HIGH]
The PCM3793A/94A supports the I
2
C serial bus and the data transmission protocol for the I
2
C standard as a
slave device. This protocol is explained in I
2
C specification 2.0.
In I
2
C mode, the control terminals are changed as follows.

The PCM3793A/94A has its own 7-bit slave address. The first six bits (MSBs) of the slave address are factory
preset to 100011. The last bit of the address byte is the device select bit, which can be user-defined by the ADR
terminal. A maximum of two PCM3793A/94As can be connected on the same bus at one time. Each
PCM3793A/94A responds when it receives its own slave address.
