Table 31. PCM Front DAC Rate Register (Index 2Ch)
Reg
No.
2Ch
This read/write Sample Rate Control Register contains 16-bit unsigned value, representing the rate of operation in Hz.
SRF[15:0]
Table 32. PCM Surround DAC Rate Register (Index 2Eh)
Reg
No.
2Eh
This read/write Sample Rate Control Register contains 16-bit unsigned value, representing the rate of operation in Hz.
This register sets the sample rate for the surround DAC. This register’s reset default is to be locked to the PCM front DAC sample rate register (2-Ch).
To unlock this register, Bit SRU in Register 76h must be asserted.
SRF[15:0]
Table 33. PCM LFE (and CENTER) DAC Rate Register (Index 30h)
Reg
No.
30h
This read/write sample rate control register contains 16-bit unsigned value, representing the rate of operation in Hz.
This register sets the sample rate for the LFE DAC and Center DAC. This register’s reset default is to be locked to the PCM Front DAC sample rate register (2-Ch)
To unlock the register bit, SRU in Register 76h must be asserted.
