*: A8 is automatically set to Low or High by a 00H command or a 01H command.
*: I/O8 must be set to Low in the third cycle.
Operation Mode: Logic and Command Tables
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.

A page consists of 528 bytes in which 512 bytes are used
An address is read in via the I/O port over three
1 page = 528 bytes
1 block = 528 bytes × 32 pages = (16K + 512) bytes
Capacity = 528 bytes × 32 pages × 1024 blocks
