NOTE:
1. tSKEW1 is the minimum time between a rising RCLK edge and a rising WCLK edge for FF to change during the current clock cycle. If the time between the rising edge of RCLK
and the rising edge of WCLK is less than tSKEW1, then FF may not change state until the next WCLK edge.
Figure 5. Write Cycle Timing
NOTES:
1. Holding WEN2/LD HIGH during reset will make the pin act as a second write enable pin. Holding WEN2/LD LOW during reset will make the pin act as a load enable for the programmable
flag offset registers.
2. After reset, the outputs will be LOW if OE = 0 and tri-state if OE = 1.
3. The clocks (RCLK, WCLK) can be free-running during reset.
