0 = Low, 1 = High
SW PCI_STP# Function
0 = SW PCI_STP# assert, 1 = SW PCI_STP# deassert
When this bit is set to 0, all STOPPABLE PCI, PCIF and SRC outputs will
be stopped in a synchronous manner with no short pulses.
When this bit is set to 1, all STOPPED PCI, PCIF and SRC outputs will
resume in a synchronous manner with no short pulses.
FS_C Reflects the value of the FS_C pin sampled on power up
0 = FS_C was low during VTT_PWRGD# assertion
FS_B Reflects the value of the FS_B pin sampled on power up
0 = FS_B was low during VTT_PWRGD# assertion
FS_A Reflects the value of the FS_A pin sampled on power up
0 = FS_A was low during VTT_PWRGD# assertion
