Read Completion Status (RCS) — R/WC. This bit indicates the status of codec read completions.
0 = A codec read completes normally.
1 = A codec read results in a time-out. The bit remains set until being cleared by software writing a
This bit is not affected by D3
Bit 3 of Slot 12 — RO. Display bit 3 of the most recent slot 12.
Bit 2 of Slot 12 — RO. Display bit 2 of the most recent slot 12.
Bit 1 of slot 12 — RO. Display bit 1 of the most recent slot 12.
ACZ_SDIN1 Resume Interrupt (S1R1) — R/WC. This bit indicates that a resume event occurred
on ACZ_SDIN1. Software clears this bit by writing a 1 to it.
0 = Resume event did Not occur
1 = Resume event occurred.
This bit is not affected by D3
ACZ_SDIN0 Resume Interrupt (S0R1) — R/WC. This bit indicates that a resume event occurred
on ACZ_SDIN0. Software clears this bit by writing a 1 to it.
0 = Resume event did Not occur
1 = Resume event occurred.
This bit is not affected by D3
ACZ_SDIN1 Codec Ready (S1CR) — RO. Reflects the state of the codec ready bit in ACZ_SDIN1.
Bus masters ignore the condition of the codec ready bits, so software must check this bit before
starting the bus masters. Once the codec is “ready”, it must never go “not ready” spontaneously.
0 = Not Ready.
1 = Ready.
ACZ_SDIN0 Codec Ready (S0CR) — RO. Reflects the state of the codec ready bit in ACZ_SDIN0.
Bus masters ignore the condition of the codec ready bits, so software must check this bit before
starting the bus masters. Once the codec is “ready”, it must never go “not ready” spontaneously.
0 = Not Ready.
1 = Ready.
Microphone In Interrupt (MINT) — RO.
0 = When the specific status bit is cleared, this bit will be cleared.
1 = One of the Mic in channel interrupts status bits has been set.
PCM Out Interrupt (POINT) — RO.
0 = When the specific status bit is cleared, this bit will be cleared.
1 = One of the PCM out channel interrupts status bits has been set.
PCM In Interrupt (PIINT) — RO.
0 = When the specific status bit is cleared, this bit will be cleared.
1 = One of the PCM in channel interrupts status bits has been set.
Reserved
Modem Out Interrupt (MOINT ) — RO.
0 = When the specific status bit is cleared, this bit will be cleared.
1 = One of the modem out channel interrupts status bits has been set.
Modem In Interrupt (MIINT) — RO.
0 = When the specific status bit is cleared, this bit will be cleared.
1 = One of the modem in channel interrupts status bits has been set.
GPI Status Change Interrupt (GSCI) — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = This bit reflects the state of bit 0 in slot 12, and is set when bit 0 of slot 12 is set. This indicates
This bit is not affected by AC ‘97 Audio Function D3
