Power Management Requirements:

Note:

1. Clock on/off latency is defined in the number of rising edges of free running PCICLKs between the clock disable goes low/

high to the first valid clock comes out of the device.

2. Power up latency is when PWR_DWN# goes inactive (high to when the first valid clocks are dirven from the device.
