NOTE:
1. t
is the minimum time between a rising RCLK edge and a
rising WCLK edge for FF to change predictably during the current
clock cycle. If the time between the rising edge of RCLK and the
rising edge of WCLK is less than t
, then it is not guaranteed
that FF will change state until the next following WCLK edge.
