Description
Defines bit position within a serial frame where the valid bit is found.
Defines bit position within a serial frame where the first data bit of
the left channel is found.
Defines bit position within a serial frame where the first data bit of
the right channel is found.
Start/Stop bit position.
If DATAMODE = MSB first, SSPOS determines the bit index (0..15)
for 16 bit samples and (0...31) for 32 bit samples, in the parallel
word of the last data bit. Bits 15 or 31 (MSB) up to and including
SSPOS are taken in order from the serial frame data. All other bits
are set to zero.
If DATAMODE = LSB first, SSPOS determines the bit index (0..15)
for 16 bit samples and (0...31) for 32 bit samples, in the parallel
word of the first data bit. Bits SSPOS up to and including 15 or 31
(MSB) are taken in order from the serial frame data. All other bits
are set to zero.

Base Address of buffer 1 must be a 64-byte aligned address in local
memory.
If changed it must be set before ACK1.
Base Address of buffer 1 must be a 64-byte aligned address in local
memory.
If changed it must be set before ACK2.
Sets number of samples in buffers before switching to other buffers.
In stereo modes, a pair of 16-bit or 32-bit data counts as 1 sample.
In mono modes, a single value counts as a sample.Buffer size in
bytes is as follows:
During raw mode the sample size is always 8 bits. Hence Buffer size
in bytes for the raw mode is SIZE.
16 bps, mono: 2 * SIZE
32 bps, mono: 4 * SIZE
16 bps, stereo: 4 * SIZE
32 bps, stereo: 8 * SIZE
