I/O
I2S serial-bit clock. In audio master mode, the AIC23B generates this signal and sends it to the
DSP. In audio slave mode, the signal is generated by the DSP.
BVDD

O
Clock output. This is a buffered version of the XTI input and is available in 1X or 1/2X frequencies
of XTI. Bit 07 in the sample rate control register controls frequency selection.
CS
