F. Repeat B through E until the entire buffer is filled or until all data within the page is loaded.
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
if less than eight bits are required to address words in the page (pagesize < 256), the most sig-
nificant bit(s) in the address low byte are used to address the page when performing a Page
Write.
G. Load Address High byte
H. Program Page
I. Repeat B through H until the entire Flash is programmed or until all data has been
programmed.
J. End Page Programming

Note:
1. Set XA1, XA0 to “00”. This enables address loading.
2. Set BS1 to “1”. This selects high address.
3. Set DATA = Address high byte (0x00 - 0xFF).
4. Give XTAL1 a positive pulse. This loads the address high byte.
1. Give WR a negative pulse. This starts programming of the entire page of data.
2. Wait until RDY/BSY goes high (See
1. 1. Set XA1, XA0 to “10”. This enables command loading.
2. Set DATA to “0000 0000”. This is the command for No Operation.
3. Give XTAL1 a positive pulse. This loads the command, and the internal write signals
RDY/BSY goes low.
