QFC timing on Write operation
QFC on writes is enabled as soon as possible after the clock edge of write command and disabled as soon
as possible after the last DQS-in low going edge.

1. The value of tQCSW min. is 1.25ns from the last low going data strobe edge to QFC tri-state.
2. The value of tQCSW max. is 0.5tcK from the first high going clock edge after the last low going data strobe
edge to QFC tri-state.
