* : A8 is automatically set to Low or High by a 00h command or a 01h command.
The Program operation works on page units while the Erase operation works on block units.
l/O2-8 must be set to Low in the fourth cycle.

A page consists of 528 bytes in which 512 bytes are
1 page = 528 bytes
1 block = 528 bytes × 32 pages = (16K + 512) bytes
Capacity = 528 bytes × 32 pages × 4096 blocks
An address is read in via the I/O port over four
consecutive clock cycles, as shown in Table 1.
