The PCM9211 also supports the I
C serial bus and data transmission protocol. It can be configured for fast mode
as a slave device. This protocol is explained fully in the
Slave Address
MSB

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.
