MPIO Description
Overview
The PCM9211 offers significant flexibility through its MPIO pins. Depending on the system partitioning of the
specific end product, the pins can be reconfigured to offer various I/Os that complement the design.
There are 14 flexible pins: 12 are Input/Output pins, and two pins that are output only.
The 12 multi-purpose I/O (MPIO) pins are grouped into three banks, each with four pins: MPIO_A, MPIO_B, and
MPIO_C.
The two multi-purpose outputs (MPO) pins are assigned as MPO0 and MPO1.
Assignable Signals for MPIO Pins
The PCM9211 has the following signals that can be brought out to MPIOs. Not all MPIOs are equal; be sure to
review subsequent sections in this document to see which signals can be brought out to which MPIO. The
possible signals are summarized in Table 11.

How to Assign Functions to MPIO
Both MPO0 and MPO1 have a function assignment register. The output of MPO0 can be selected using the
MPO0SEL[3:0] register; in the same way, the output of MPO1 can be selected using the MPO1SEL[3:0] register.
Selecting the biphase source can be done using Register 35h/RO0SEL and Register 36h/RO1SEL. Muting the
MPO can be done using Registers MPO0MUT and MPO1MUT.
Selection Of Output Source
The PCM9211 also has a routing function for serial digital audio clocks and data. This function routes between all
input sources (DIR, ADC, AUXIN0, AUXIN1, AUXIN2) and Main Out, AUXOUT, and DIT. The selection for Main
Out and AUXOUT is set with these registers:
Main Out: Registers 6Bh, MOSSRC[2:0], and MOPSRC[2:0]
AUXOUT: Register 6Ch, AOSSRC[2:0], and AOPSC[2:0]
