4.1.3.2 OE Pin Control

LMKDB1120EVM has on-board IO expander to provide output enable and disable controls for OE# pins. Low and high voltage levels can be set on all the pins using GUI without needing on-board headers. If on-board headers are used, then set all the OE# pins to Hi-Z using the All Hi-Z button under the OE Pin Control on output page.
