Field Name Bits Default Description
Wake Enable 3:0 0h This field controls which SDIN signals may generate a
wake event in response to a codec State Change event.
Bit[0] corresponds to Codec 0 – SDIN[0]
Bit[1] corresponds to Codec 1 – SDIN[1]
Bit[2] corresponds to Codec 2 – SDIN[2]
Bit[3] corresponds to Codec 3 – SDIN[3]
These bits are only cleared by a power-on reset.
Reserved 15:4 000h Reserved. Software must do a read-m odify-write to
preserve the value of these bits.

State Change Status
Flags
3:0 0h This field indicates which SDIN signal(s) rec eived a State
Change event.
Bit[0] corresponds to Codec 0 – SDIN[0]
Bit[1] corresponds to Codec 1 – SDIN[1]
Bit[2] corresponds to Codec 2 – SDIN[2]
Bit[3] corresponds to Codec 3 – SDIN[3]
These bits are cleared by writing 1’s to them.
These bits are only cleared by a power-on reset.
Reserved (R/W) 15:4 000h Reserved. Software must do a read-m odify-write to
preserve the value of these bits.
Field Name Bits Default Description
Reserved 0 0b Reserved. Software must use 0 for write to this bit.
Flush Status 1 0b T his bit is set to a “1” by hardware to indicate that the flush
cycle initiated by setting the Flush Control has completed.
Software must write a “1” to clear this bit before the next
time Flush Control is set.
Reserved 15:2 0000h Reserved. Software must use 0’s for write to these bits.
Field Name Bits Default Description
Output Stream Payload
Capability
15:0 003Ch This field indicates the maximum number of words per
frame for any single output stream. This measurement is in
16-bit word quantities per 48 kHz frame. The value must
not be greater than the Output Payload Capability register
value. Software must ensure that a format which would
cause more words per frame than indicated is not
programmed into the Output Stream Descriptor register.
00h: No Limit ( Stream size is limited only by Output
Payload Capability register)
01h: 1 word payload
:
:
FFh: 255 word payload
