Enable signal
In read mode (R/W=H), data appears at DB0 to DB7
while E is H.
In write mode (R/W=L), data of DB0 to DB7 is latched
at the falling edge of E.
In 8-bit mode, used as low order bi-directional data
bus.
In 4-bit mode, open these terminals.
In 8-bit mode, used as high order bi-directional data
bus.
In 4-bit mode, used as both high and low order data
bus.
