PCI_STOP# Timing Diagram
PCI_STOP# is an input to the clock synthesizer and must be made synchronous to the clock driver PCICLK_F output.
It is used to turn off the PCI clocks for low power operation. PCI clocks are required to be stopped in a low state and
started such that a full high pulse width is guaranteed. ONLY one rising edge of PCICLK_F is allowed after the clock
control logic switched for the PCI outputs to become enabled/disabled.
Notes:
1. All timing is referenced to CPUCLK.
2. Internal means inside the chip.
3. All other clocks continue to run undisturbed.
4. PD# and CPU_STOP# are shown in a high state.
5. Diagrams shown with respect to 133MHz. Similar operation when CPU is 100MHz.
