C. Load Data Low Byte
D. Load Data High Byte
E. Latch Data
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
programmed.
1. Set XA1, XA0 to “01”. This enables data loading.
2. Set DATA = Data low byte (0x00 – 0xFF).
3. Give CLKI a positive pulse. This loads the data byte.
1. Set BS1 to “1”. This selects high data byte.
2. Set XA1, XA0 to “01”. This enables data loading.
3. Set DATA = Data high byte (0x00 – 0xFF).
4. Give CLKI a positive pulse. This loads the data byte.
1. Set BS1 to “1”. This selects high data byte.
2. Give PAGEL a positive pulse. This latches the data bytes. (See
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 CLKI 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
waveforms)
RDY/BSY goes low.
