PCM In 2, Microphone In 2 Data In Line (DI2L)— R/W. When the SE bit is set,
these bits indicates which ACZ_SDIN line should be used by the hardware for decoding
the input slots for PCM In 2 and Microphone In 2. When the SE bit is cleared, the value
of these bits are irrelevant, and PCM In 2 and Mic In 2 DMA engines are not available.
00 = ACZ_SDIN0
01 = ACZ_SDIN1
10 = ACZ_SDIN2
11 = Reserved
PCM In 1, Microphone In 1 Data In Line (DI1L)— R/W. When the SE bit is set,
these bits indicates which ACZ_SDIN line should be used by the hardware for decoding
the input slots for PCM In 1 and Microphone In 1. When the SE bit is cleared, the value
of these bits are irrelevant, and the PCM In 1 and Mic In 1 engines use the OR’d
ACZ_SDIN lines.
00 = ACZ_SDIN0
01 = ACZ_SDIN1
10 = ACZ_SDIN2
11 = Reserved
Steer Enable (SE) — R/W. When set, the ACZ_SDIN lines are treated separately and
not OR’d together before being sent to the DMA engines. When cleared, the ACZ_SDIN
lines are OR’d together, and the “Microphone In 2” and “PCM In 2” DMA engines are not
available.
Reserved — RO.
Last Codec Read Data Input (LDI) — RO. When a codec register is read, this
indicates which ACZ_SDIN the read data returned on. Software can use this to
determine how the codecs are mapped. The values are:
00 = ACZ_SDIN0
01 = ACZ_SDIN1
10 = ACZ_SDIN2
11 = Reserved
