register 2Ch to 32h – audio sample rate control registers
These registers are read/write registers—writing to this registers is done to select alternative sample rates for
the audio PCM converters. The default rate is 48 ksps. Note that only Revision 2.1-recommended rates are
supported by the TLV320AIC27; selection of any other unsupported rates causes the rate to default to the
nearest supported rate, and the supported rate value to be latched and therefore, read back.
Register 2Ch is the front DAC rate register, but it is also used for center channel data rate.
I2S mode only supports 48 ksps rates, not variable rates.
