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
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.
