PCMRI
Receive PCM data input.
This PCM input signal is shifted on the falling edge of BCLK and input from MSB.
BCLK
Shift clock input for the PCM data (PCMSO, PCMRI).
The frequency is set in the range of 64 kHz to 2048 kHz.
XSYNC
8 kHz synchronous signal input for Transmit PCM data.
This signal should be synchronized with BCLK. XSYNC is used for indicating MSB of the
transmit serial PCM.
Be sure to input the XSYNC signal because it is also used as the input of the timing circuit and
the clock source of the tone generator.
RSYNC
8 kHz synchronous signal input for Receive PCM data.
This signal should be synchronized with BCLK signal. RSYNC is used for indicating the MSB
of the receive serial PCM.
