AGP_STOP# Timing Diagram
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
ICS4228
.
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.
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
ICS94228
. 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 3 AGPCLKs. This function is available only with MODE pin latched low.
CPU_STOP# Timing Diagram
CPU_STOP# is an asychronous input to the clock synthesizer. It is used to turn off the CPUCLKs for low power
operation. CPU_STOP# is synchronized by the
ICS94228
. All other clocks will continue to run while the CPUCLKs
clocks are disabled. The CPUCLKs will always be stopped in a low state and start in such a manner that guarantees
the high pulse width is a full pulse. CPUCLK on latency is less than 4 CPUCLKs and CPUCLK off latency is less than
4 CPUCLKs.
