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
eight bits are 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.
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 pro-
grammed.
J. End Page Programming

Note:
1. Set XA1, XA0 to “0,0”. 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. Set XA1, XA0 to “1,0”. This enables command loading.
