Programmable Registers
36.3.4 SPDIF Sample Rate Register (HW_SPDIF_SRR)
The SPDIF Sample Rate Register controls the sample rate of the data stream played back
from the circular buffer.
HW_SPDIF_SRR: 0x030
HW_SPDIF_SRR_SET: 0x034
HW_SPDIF_SRR_CLR: 0x038
HW_SPDIF_SRR_TOG: 0x03C
The SPDIF Sample Rate Register provides a RATE field for specifying the sample rate
conversion factor to use in outputting the current SPDIF stream.
EXAMPLE
HW_SPDIF_SRR.B.RATE = 0x0AC44; // 44.1KHz
