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.
