While the lower bits in the address are mapped to words within the page, the higher bits address
the pages within the FLASH. This is illustrated in
required to address words in the page (pagesize < 256), the most significant bit(s) in the address
low byte are used to address the page when performing a Page Write.

9. End Page Programming:
a. Set XA1, XA0 to “01”. This enables data loading.
b. Set DATA = Data low byte (0x00 - 0xFF).
c. Give XTAL1 a positive pulse. This loads the data byte.
a. Set BS1 to “1”. This selects high data byte.
b. Keep XA1, XA0 at “01”. This enables data loading.
c. Set DATA = Data high byte (0x00 - 0xFF).
d. Give XTAL1 a positive pulse. This loads the data byte.

a. Set XA1, XA0 to “00”. This enables address loading.
b. Set BS1 to “1”. This selects high address.
c. Set DATA = Address high byte (0x00 - 0xFF).
d. Give XTAL1 a positive pulse. This loads the address high byte.
a. Give WR a negative pulse. This starts programming of the entire page of data.
b. Wait until RDY/BSY goes high.
