Notes:
12. The clocks (RCLKA,RCLKB, WCLKA,WCLKB) can be free-running during reset.
13. After reset, the outputs will be LOW if (OEA,OEB) = 0 and three-state if (OEA,OEB)=1.
14. Holding (WENA2/LDA,WENB2/LDB) HIGH during reset will make the pin act as a second enable pin. Holding(WENA2/LDA,WENB2/LDB) LOW during reset will make the
