DATASHEET
This register indicates the state of the individual PME sources,
independent of the individual source enables or the PME_En bit.
If the PME source has asserted an event, the associated PME
Status bit will be a “1”.
Bit[0] GP34
Bit[1] GP35
Bit[2] GP36
Bit[3] GP37
Bit[4] Reserved
Bit[5] Reserved
Bit[6] Reserved
Bit[7] GP62
The PME Status register is not affected by Vcc POR, SOFT
RESET or PCI RESET.
Writing a “1” to Bit[4:0] will clear it. Writing a “0” to any bit in PME
Status Register has no effect.
PME Enable Register 7
This register is used to enable individual PME wake sources onto
the IO_PME# wake bus.
Bit[0] GP34
Bit[1] GP35
Bit[2] GP36
Bit[3] GP37
Bit[4] Reserved
Bit[5] Reserved
Bit[6] Reserved
Bit[7] GP62
Vcc_CNT1 (Byte 1)
This register contains the Least Significant Byte (LSB) of the 32 bit
VCC Power On Elapsed Time Counter.
Bit[7:0] = Bit[7:0] of the 32-bit VCC Power-On-Elapsed-Time
Vcc_CNT2 (Byte 2)
Bit[7:0] = Bit[15:8] of the 32-bit VCC Power-On-Elapsed-Time
Vcc_CNT3 (Byte 3)
Bit[7:0] = Bit[23:16] of the 32-bit VCC Power-On-Elapsed-Time
Vcc_CNT4 (Byte 4)
This register contains the Most Significant Byte (MSB) of the 32 bit
VCC Power On Elapsed Time Counter.
Bit[7:0] = Bit[31:24] of the 32-bit VCC Power-On-Elapsed-Time
Vtr_CNT1 (Byte 1)
This register contains the Least Significant Byte (LSB) of the 32 bit
VTR Power On Elapsed Time Counter.
Bit[7:0] = Bit[7:0] of the 32-bit VTR Power-On-Elapsed-Time
