NOTE:
1. tSKEW2 is the minimum time between a rising WCLK edge and a
rising RCLK edge for EF to change predictably during the current
clock cycle. If the time between the rising edge of WCLK and the
rising edge of RCLK is less than tSKEW2, then it is not guaranteed
that EF will change state until the next following RCLK edge.
