All PCI and SRC Clock outputs
except PCIF and SRC clocks
set to free-running
PCI_STP Control. 0 = SW PCI_STP not enabled and only the PCI_STP# pin will
stop the PCI stop enabled outputs, 1 = the PCI_STP function is enabled and the
stop enabled outputs will be stopped in a synchronous manner with no short pulses.
