Programming the Flash
The Flash is organized in pages, see
the program data is latched into a page buffer. This allows one page of program data to be
programmed simultaneously. The following procedure describes how to program the entire
Flash memory:
A. Load Command “Write Flash”
B. Load Address Low byte
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
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.
1. Set XA1, XA0 to “1,0”. This enables command loading.
2. Set BS1 to “0”.
3. Set DATA to “0001 0000
4. Give XTAL1 a positive pulse. This loads the command.
1. Set XA1, XA0 to “00”. This enables address loading.
2. Set BS1 to “0”. This selects low address.
3. Set DATA = Address low byte (0x00 - 0xFF).
4. Give XTAL1 a positive pulse. This loads the address low byte.
1. Set XA1, XA0 to “0,1”. This enables data loading.
2. Set DATA = Data low byte (0x00 - 0xFF).
3. Give XTAL1 a positive pulse. This loads the data byte.
1. Set BS1 to “1”. This selects high data byte.
2. Set XA1, XA0 to “0,1”. This enables data loading.
3. Set DATA = Data high byte (0x00 - 0xFF).
4. Give XTAL1 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
waveforms)
