Description
DMA buffer size in samples. The number of mono samples or stereo
sample pairs is read from a DMA buffer in memory before switching
to the other DMA buffer in memory. Buffer size in bytes is as follows:
16 bps, mono: 2 * SIZE
32 bps, mono: 4 * SIZE
16 bps, stereo: 4 * SIZE
32 bps, stereo: 8 * SIZE
To ensure software backward compatibility unused or reserved bits must
be written as zeros and ignored upon read
The 16-bit value of CC1 is shifted into each emitted serial frame
starting at bit position CC1_POS, as long as CC1_EN is asserted.
The 16-bit value of CC2 is shifted into each emitted serial frame
starting at bit position CC2_POS, as long as CC2_EN is asserted.
To ensure software backward compatibility unused or reserved bits must
be written as zeros and ignored upon read
Defines the bit position within a serial frame where the first data bit
of CC1 is placed.
Defines the bit position within a serial frame where the first data bit
of CC2 is placed.
A read returns 0xDEADABBA.
To ensure software backward compatibility unused or reserved bits must
be written as zeros and ignored upon read
The bit is used to provide power control status for system software
block power management.
Module ID. This field identifies the block as type Audio Out.
Major Revision ID. This field is incremented by 1 when changes
introduced in the block result in software incompatibility with the
previous version of the block. First version default = 0.
Minor Revision ID. This field is incremented by 1 when changes
introduced in the block result in software compatibility with the
previous version of the block. First version default = 0.
Aperture size. Identifies the MMIO aperture size in units of 4 KB for
the AO block. AO has an MMIO aperture size of 4 KB.
Aperture = 0: 4 KB.
