Notes:
1. All timing is referenced to the Internal CPUCLK (defined as inside the ICS9248 device.)
2. PCI_STOP# is an asynchronous input, and metastable conditions may exist. This signal is required to be synchronized
3. All other clocks continue to run undisturbed.
4. CPU_STOP# is shown in a high (true) state.

PCI_STOP# Timing Diagram
PCI_STOP# is an asynchronous input to the ICS9248-39. It is used to turn off the PCICLK (0:4) clocks for low power
operation. PCI_STOP# is synchronized by the ICS9248-39 internally. The minimum that the PCICLK (0:4) clocks are
enabled (PCI_STOP# high pulse) is at least 10 PCICLK (0:4) clocks. PCICLK (0:4) clocks are stopped in a low state
and started with a full high pulse width guaranteed. PCICLK (0:4) clock on latency cycles are only one rising PCICLK
clock off latency is one PCICLK clock.
