The PCI_STOP# signal is on an active low input controlling PCI and SRC outputs. If PCIF (2:0) and SRC clocks can be set to
be free-running through I2C programming. Outputs set to be free-running will ignore both the PCI_STOP pin and the
PCI_STOP register bit.

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[2:0] 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 Iref * 6 (or tristate if Byte 2 Bit 6 = 1) upon its next low to high transition and
the SRC# will latch low as shown below.

PCI_STOP# Assertion (transition from '1' to '0')
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, all PCI[6:0], stoppable PCIF[2:0] and stoppable SRC clocks will resume in a glitch free
manner.
