CE Chip Enable (active Low). This pin is active during EPROM Read Mode, Program
Mode, and Program Verify Mode.
OE Output Enable (active Low). This pin drives the direction of the Data Bus. When this
pin is Low, the Data Bus is output, when High, the Data Bus is input.
EPM EPROM Program Mode. This pin controls the different EPROM Program Mode by
applying different voltages.

PGM Program Mode (active Low). When this pin is Low, the data is programmed to the
EPROM through the Data Bus.
