within the module.
Pin Name Pin Number Signal Direction Description
PCM_RX 12 I Serial Data Input
PCM_TX 18 O Serial Data Output
PCM_CLK 14 IO Serial Clock I/O
PCM_FSYNC 16 IO Frame Synchronization I/O
32 KHz Output (PIN 56)
A 32.768 kHz signal is available as an output from the module. This signal should only be used
as an input to a high impedance device. Additional loads or capacitance on the line may cause
performance issues with the module. If the line is not used, leave floating.
