R/W PME_Status
Set if PME# condition exists regardless of state of PME_En bit. A
clear
write of a 1 to this bit clears the PME condition.
14:13 R Not Implemented 0H -Data Field not implemented, therefore data scale read only
12:9 R Not Implemented 0H -Data Field not implemented, therefore data select read only

Whenever this register is written such that the value of the Power State bits change, an interrupt will be
generated. This will appear on the INTA# pin if the PWRINTEN bit is set in the Interrupt Control Register.
The interrupt is cleared by writing the CURPDLEV bits in the interrupt control register to equal the value of
the Power State bits.
7. REGISTER MAP
All Control registers in AudioPCI 97 are addressed in the direct PCI I/O space. There are control registers
for each of the major blocks of the AUDIOPCI system. The memory map is shown below:
