Reset Timing
Notes:
13. The clocks (RCLK, WCLK) can be free-running during reset.
14. After reset, the outputs will be LOW if OE = 0 and three-state if OE=1.
15. Holding WEN2/LD HIGH during reset will make the pin act as a second enable pin. Holding WEN2/LD LOW during reset will make the pin act as a load enable
WEN2/LD
for the programmable flag offset registers.
