NOTES:
1. When SRCCLK outputs controlled by CLKREQA# and CLKREQB# are enabled, clock output behavior will follow SMBus control bits (per CK410 spec).
2. Assertion/de-assertion time of CLKREQ# pins will match PCI_STOP# timing of the CK410 spec. This is 15ns from the assertion/de-assertion of CLKREQ# to the drive/tie-state
