36.3.5 SPDIF Debug Register (HW_SPDIF_DEBUG)
The SPDIF Debug Register provides read-only access to various internal state information
that may be useful for block debugging and validation.
HW_SPDIF_DEBUG: 0x040
HW_SPDIF_DEBUG_SET: 0x044
HW_SPDIF_DEBUG_CLR: 0x048
HW_SPDIF_DEBUG_TOG: 0x04C
This is a read-only register used for checking FIFO status and PIO mode of operation.
EXAMPLE
unsigned TestBit = HW_SPDIF_DEBUG.DMA_PREQ;
