PCI STOP FUNCTIONALITY
programming, they will ignore both the PCI_STOP# pin and the PCI_STOP register bit.
PCI_STOP# - DE-ASSERTION
all PCI[6:0], stoppable PCIF[1:0] and stoppable SRC clocks will resume in a glitch free manner.
PCI_STOP# ASSERTION (TRANSITION FROM ‘1’ TO ‘0’)
clocks will latch low on their next high to low transition. After the PCI clocks are latched low, the SRC clock, (if set to stoppable) will latch high at I
tristate if Byte 5 Bit 7 = 1) upon its next low to high transition and the SRC# will latch low as shown below.

PROGRAMMABLE FLEXPC CLOCK FOR P4 PROCESSOR
PCI_STOP#
The PCI_STOP# signal is on an active low input controlling PCI and SRC outputs. If PCIF[1:0] and SRC clocks can be set to be free-running through SMBus
The de-assertion of the PCI_STOP# signal is to be sampled on the rising edge of the PCIF free running clock domain. After detecting PCI_STOP# de-assertion,
The clock samples the PCI_STOP# signal on a rising edge of PCIF clock. After detecting the PCI_STOP# assertion low, all PCI[6:0] and stoppable PCIF[1:0]
