A page consists of 528 bytes in which 512 bytes are used for
main memory storage and 16 bytes are for redundancy or for
other uses.

An address is read in via the I/O port over four consecutive
clock cycles, as shown in Table 1.

Operation Mode: Logic and Command Tables
The operation modes such as Program, Erase, Read and Reset are controlled by the nineteen different
command operations shown in Table 3. Address input, command input and data input/output are controlled by
the CLE, ALE, CE , WE , RE and WP signals, as shown in Table 2.
