Table 17-20. Power Management Timings
NOTES:
1. These transitions are clocked off the internal RTC. 1 RTC clock is approximately 32 µs.
2. This transition is clocked off the 66 MHz CLK66. 1 CLK66 is approximately 15 ns.
3. The ICH4 STPCLK# assertion will trigger the processor to send a stop grant acknowledge cycle. The timing
4. These transitions are clocked off the 33 MHz PCICLK. 1 PCICLK is approximately 30 ns.
5. The ICH4 has no maximum timing requirement for this transition. It is up to the system designer to determine
