Byte 0: Control Register
Byte 1: Control Register
Notes:
1. R= Read only RW= Read and Write
2. PWD = Power on Default
3. The purpose of this bit is to allow a system designer to implement PCI_STOP functionality in one of two ways. Wither the
system designer can choose to use the externally provided PCI_STOP# pin to assert and de-assert PCI_STOP
functionality via I
2C Byte 0 Bit 3.
In Hardware mode it is not allowed to write to the I
2C 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 I
2C 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 (I
2C Byte 0 Bit 3 = 0)].
4. For disabled clocks, they stop low for single ended clocks. Differential CPU clocks stop with CPUCLKT at high, CPUCLKC
off, and external resistor termination will bring CPUCLKC low.
