ICS9148-14
PCI_STOP# Timing Diagram
PCI_STOP# is an asynchronous input to theICS9148-14. It is used to turn off theAGP, E_PCICLK and PCICLK (0:4) clocks for
low power operation. PCI_STOP# is synchronized by the ICS9148-14 internally. The minimum that the PCICLK clocks are
enabled (PCI_STOP# high pulse) is at least 10 PCICLK clocks. PCICLK clocks are stopped in a low state and started with a full
high pulse width guaranteed. PCICLK clock on latency cycles are only one rising PCICLK clock off latency is one PCICLK clock.
Notes:
1. All timing is referenced to the Internal CPUCLK (defined as inside the ICS9148 device.)
2. PCI_STOP# is an asynchronous input, and metastable conditions may exist. This signal is required to be synchronized
inside the ICS9148.
3. All other clocks continue to run undisturbed.
4. PWR_DWN# and CPU_STOP# are shown in a high (true) state.
5. See Power Management Functionality table, when CPU_STOP# and PCI_STOP# are Both Low, the SDRAM clocks are also stopped in the Low
state outputs.
