on operation.
No Connects. Not connected to the die.
Write Enable Input, Active LOW. When selected LOW, a write is
conducted. When deselected HIGH, a read is conducted.
Chip Enable Input, Active LOW. When LOW, selects the chip.
When HIGH, deselects the chip.
Byte Write Select Inputs, Active LOW. BHE controls IO
BLE controls IO
Output Enable, Active LOW. Controls the direction of the IO pins.
When LOW, the IO pins are allowed to behave as outputs. When
deasserted HIGH, the IO pins are tri-stated and act as input data
pins.
Ground for the Device. Connected to ground of the system.
