AGP_STOP# Timing Diagram
AGP_STOP# is an asychronous input to the clock synthesizer. It is used to turn off the AGP clocks. for low power operation.
AGP_STOP# is synchronized by the ICS9248-131. The AGPCLKs will always be stopped in a low state and start in such a
manner that guarantees the high pulse width is a full pulse. AGPCLK on latency is less than AGPCLK and AGPCLK off latency
is less than 4 AGPCLKs. This function is available only with MODE pin latched low.
Notes:
1. All timing is referenced to the internal CPUCLK.
2. AGP_STOP# is an asynchronous input and metastable conditions may exist.
This signal is synchronized to the CPUCLKs inside the ICS9248-131.
3. All other clocks continue to run undisturbed.
4. PD# and PCI_STOP# are shown in a high (true) state.
5. Only applies if MODE pin latched 0 at power up.
