Functional Description
The device can also be configured as an 8 and 16-bit device by grounding the unused pins in Configurations 2 and 1
respectively. The 8-bit configuration may also be achieved by tying two of the 4-bit enables from configuration together and
tying the remaining enable pin (OE) HIGH.
