ZHCSIM2D June 2010 – August 2021 PCM9211
PRODUCTION DATA
The PCM9211 includes 12 MPIO (Multi-Purpose Inputs/Outputs) and two MPO (Multi-Purpose Output) pins. These MPIO/MPO pins can be easily set to different configurations through registers to allow different routing and provide data outputs based on the specific application.
The 12 MPIO pins are divided into three groups (A, B, and C); each group has four pins (MPIO_Ax, MPIO_Bx, and MPIO_Cx).
For example, to access all 12 S/PDIF inputs, the MPIO_Ax pins can be configured to support S/PDIF RXIN8 and RXIN11. However, if the application requires an additional I2S input, then the MPIO_Ax pins can be configured for an Aux In instead of RXIN8 and RXIN11.
