Input/Control
Write Enable Input, active LOW.
When selected LOW, a WRITE is
conducted. When selected HIGH, a READ is conducted.
Input/Control
Chip Enable Input, active LOW.
When LOW, selects the chip. When
HIGH, deselects the chip.
Input/Control
Output Enable, active LOW.
Controls the direction of the I/O pins.
When LOW, the I/O pins are allowed to behave as outputs. When
deasserted HIGH, I/O pins are three-stated, and act as input data
pins.
Ground
