WRITE OPERATIONS
The following operations are initiated by observing the
sequence specified in the Write Command Table.
Read Mode
The device can be put into a standard READ mode by
initiating a write cycle with 00H on the data bus. The
subsequent read cycles will be performed similar to a
standard EPROM or E
