C

Return internal clocks to full speed and assert

PROCRDY.

	3	Deassert PROCRDY and slow down internal clocks.
	4	Processor wake-up event or CONNECT asserted by

	5	CLKFWDRST is deasserted by the Northbridge.

	6	Forward clocks start three SYSCLK periods after
	6	CLKFWDRST is deasserted.
		CLKFWDRST is deasserted.

Note:

*The Connect special cycle is only issued after a processor wake-up event (interrupt or STPCLK# deassertion) occurs. If the AMD Athlon™ system bus is connected so the Northbridge can probe the processor, a Connect special cycle is not issued at that time (it is only issued after a subsequent processor wake-up event).
