NOTES:
1. Clock ON/OFF latency is defined as the number of rising edges of free running PCICLKs between the clock disable goes HIGH/LOW to the
first valid clock that comes out of the device.
2. Power up latency is when PWRDWN goes inactive (HIGH) to when the first valid clocks are driven from the device.
