S_CLK is produced by the LM4935 and the I
2
S_CLK pin will be an output.
If set the PCM_SYNC is produced by the LM4935 and the relevant pin will be an output.
If set the PCM_CLK is produced by the LM4935 and the relevant pin will be an output.
The two ADCs on the LM4935 can both be read via the isochronous I2S interface. The most recent
valid sample is output from the following source: (Please refer to the GPIO configuration register
