system designer can choose to use the externally provided PCI_STOP# pin to assert and de-assert PCI_STOP
functionality via SMBus Byte 0 Bit 3.
In Hardware mode it is not allowed to write to the SMBus Byte 0 Bit3. In Software mode it is not allowed to pull the
external PCI_STOP pin low. This avoids the issues related with Hardware started and software stopped PCI_STOP
conditions. The clock chip is to be operated in the Hardware or Software PCI_STOP mode ONLY, it is not allowed to mix
these modes.
In Hardware mode the SMBus byte 0 Bit 3 is R/W and should reflect the status of the part. Whether or not the chip is in
PCI_STOP mode.
Functionality PCI_STOP mode should be entered when [(PCI_STOP#=0) or (SMBus Byte 0 Bit 3 = 0)].
