AD1986A
SURROUND DAC PCM RATE (REGISTER 0x2E)
This read/write sample rate control register contains a 16-bit unsigned value, representing the rate of operation in Hz. If the VRA bit
(0x2A D00) is 0, this register is forced to 48 kHz (0xBB80). If VRA is 1, this register can be programmed with the actual sample rate.
If the DRA bit (0x2A D01) is set, the surround DAC is inoperative and automatically powered down.

C/LFE DAC PCM RATE (REGISTER 0x30)
This read/write sample rate control register contains a 16-bit unsigned value, representing the rate of operation in Hz. If the VRA bit
(0x2A D00) is 0 this register is forced to 48 kHz (0xBB80). If VRA is 1, this register can be programmed with the actual sample rate.
If the DRA bit (0x2A D01) is set, the C/LFE DAC is inoperative and automatically powered down.

ADC PCM RATE (REGISTER 0x32)
This read/write sample rate control register contains 16-bit unsigned value, representing the rate of operation in Hz. If the VRA bit (0x2A
D00) is 0 (zero) this register is forced to 48 kHz (0xBB80). If VRA is 1, this register can be programmed with the actual sample rate.

Function
The sampling frequency range is from 7 kHz (0x01B58) to 48 kHz (0xBB80) in 1 Hz increments. If zero is written to VRA then the
sample rates are reset to 48 kHz.
