ACZ_SDIN2 Interrupt Enable (S2RE) — R/W.
0 = Disable.
1 = Enable an interrupt to occur when the codec on the ACZ_SDIN2 causes a resume event on
ACZ_SDIN1 Resume Interrupt Enable (S1RE) — R/W.
0 = Disable.
1 = Enable an interrupt to occur when the codec on the ACZ_SDIN1 causes a resume event on
ACZ_SDIN0 Resume Interrupt Enable (S0RE) — R/W.
0 = Disable.
1 = Enable an interrupt to occur when the codec on ACZ_SDIN0 causes a resume event on the
AC-LINK Shut Off (LSO) — R/W.
0 = Normal operation.
1 = Controller disables all outputs which will be pulled low by internal pull down resistors.
AC ’97 Warm Reset — R/W (special).
0 = Normal operation.
1 = Writing a 1 to this bit causes a warm reset to occur on the AC-link. The warm reset will awaken
AC ’97 Cold Reset# — R/W.
0 = Writing a 0 to this bit causes a cold reset to occur throughout the AC ‘97 circuitry. All data in
1 = This bit defaults to 0 and hence after reset, the driver needs to set this bit to a 1. The value of

GPI Interrupt Enable (GIE) — R/W. This bit controls whether the change in status of any GPI
causes an interrupt.
0 = Bit 0 of the Global Status Register is set, but no interrupt is generated.
1 = The change on value of a GPI causes an interrupt and sets bit 0 of the Global Status Register.

minimum number of ms have elapsed.
this bit is retained after suspends; hence, if this bit is set to a 1 prior to suspending, a cold reset
