NOTE:

1. tSKEW2 is the minimum time between a rising WCLK edge and a

rising RCLK edge for HF 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 HF will change state until the next following RCLK edge.

2. The internal state of the FIFO:
