The bits in this register contain second level SMI status reporting. Top level is reported at F1BAR0+I/O Offset 00h/02h[1].
Reading this register does not clear the status bits. See F3BAR0+Memory Offset 10h.
Description
Audio Bus Master 2 SMI Status. Indicates if an SMI was caused by an event occurring on Audio Bus Master 2.
0: No.
1: Yes.
SMI generation is enabled when Audio Bus Master 2 is enabled (F3BAR0+Memory Offset 30h[0] = 1).
An SMI is then generated when the End of Page bit is set in the Audio Bus Master 2 SMI Status Register (F3BAR0+Memory
Offset 31h[0] = 1).
Audio Bus Master 1 SMI Status. Indicates if an SMI was caused by an event occurring on Audio Bus Master 1.
0: No.
1: Yes.
SMI generation is enabled when Audio Bus Master 1 is enabled (F3BAR0+Memory Offset 28h[0] = 1).
An SMI is then generated when the End of Page bit is set in the Audio Bus Master 1 SMI Status Register (F3BAR0+Memory
Offset 29h[0] = 1).
Audio Bus Master 0 SMI Status. Indicates if an SMI was caused by an event occurring on Audio Bus Master 0.
0: No.
1: Yes.
SMI generation is enabled when Audio Bus Master 0 is enabled (F3BAR0+Memory Offset 20h[0] = 1).
An SMI is then generated when the End of Page bit is set in the Audio Bus Master 0 SMI Status Register (F3BAR0+Memory
Offset 21h[0] = 1).
Codec Serial or GPIO Interrupt SMI Status. Indicates if an SMI was caused by a serial or GPIO interrupt from codec.
0: No.
1: Yes.
SMI generation enabling for codec serial interrupt: F3BAR0+Memory Offset 08h[23] = 1.
SMI generation enabling for codec GPIO interrupt: F3BAR0+Memory Offset 00h[30] = 1.
I/O Trap SMI Status. Indicates if an SMI was caused by an I/O trap.
0: No.
1: Yes.
The next level (third level) of SMI status reporting is at F3BAR0+Memory Offset 14h.
Reserved. Must be set to 0.
Audio Bus Master 5 SMI Status. Indicates if an SMI was caused by an event occurring on Audio Bus Master 5.
0: No.
1: Yes.
SMI generation is enabled when Audio Bus Master 5 is enabled (F3BAR0+Memory Offset 48h[0] = 1). An SMI is then gen-
erated when the End of Page bit is set in the SMI Status Register (F3BAR0+Memory Offset 49h[0] = 1). The End of Page bit
must be cleared before this bit can be cleared.
Audio Bus Master 4 SMI Status. Indicates if an SMI was caused by an event occurring on Audio Bus Master 4.
0: No.
1: Yes.
SMI generation is enabled when Audio Bus Master 4 is enabled (F3BAR0+Memory Offset 40h[0] = 1). An SMI is then gen-
erated when the End of Page bit is set in the SMI Status Register (F3BAR0+Memory Offset 41h[0] = 1). The End of Page bit
must be cleared before this bit can be cleared.
Audio Bus Master 3 SMI Status. Indicates if an SMI was caused by an event occurring on Audio Bus Master 3.
0: No.
1: Yes.
SMI generation is enabled when Audio Bus Master 3 is enabled (F3BAR0+Memory Offset 38h[0] = 1). An SMI is then gen-
erated when the End of Page bit is set in the SMI Status Register (F3BAR0+Memory Offset 39h[0] = 1). The End of Page bit
must be cleared before this bit can be cleared.
