8.3.5 PCM Configuration
For voice and assisted audio features, the PCM signals from CC2564MODN (master) must be connected to an
external audio host (slave). This relationship signifies that the CC2564MODN board provides the FSYNC and
slow clock signals to the codec.
The PCM configuration is required for the following profiles:
• HFP
• HSP
• A3DP
Two configurations are available for the two connectors: EM and COM. Figure 8-7 demonstrates the default
configuration and the following sections show how to set up each connector.
