ACZ_SDIN2 Resume Interrupt (S2RI) — R/WC. This bit indicates a resume event occurred on
ACZ_SDIN2. 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_SDIN2 Codec Ready (S2CR)
ACZ_SDIN2. 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.
Bit Clock Stopped (BCS)
0 = Transition is found on BIT_CLK.
1 = ICH6 detected that there has been no transition on BIT_CLK for four consecutive PCI clocks.
S/PDIF Interrupt (SPINT)
0 = When the specific status bit is cleared, this bit will be cleared.
1 = S/PDIF out channel interrupt status bits have been set.
PCM In 2 Interrupt (P2INT)
0 = When the specific status bit is cleared, this bit will be cleared.
1 = One of the PCM In 2 channel status bits have been set.
Microphone 2 In Interrupt (M2INT)
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.

MD3 — R/W. Power down semaphore for Modem. This bit exists in the suspend well and maintains
context across power states (except G3). The bit has no hardware function. It is used by software in
conjunction with the AD3 bit to coordinate the entry of the two codecs into D3 state.
This bit is not affected by D3
