Two-Wire (I
2C) Serial Control
The PCM9211 also supports the I2C serial bus and data transmission protocol. It can be configured for fast mode
as a slave device. This protocol is explained fully in the I2C specification 2.1.

R/W
The PCM9211 has seven bits for its own slave address. The first five bits (MSB) of the slave address are
factory-preset to '10000'. The next two bits of the address byte are selectable bits that can be set by MDO/ADR0
and MS/ADR1. A maximum of four PCM9211s can be connected on the same bus at one time. Each PCM9211
responds when it receives its own slave address.
