Programming the Flash
Load Command “Chip Erase”
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”
Give XTAL1 a positive pulse. This loads the command.
B. Load Address Low byte
C. Load Data Low Byte
D. Load Data High Byte
E. Latch Data
1. Set XA1, XA0 to “1,0 ”. This enables command loading.
2. Set BS1 to “0”.
3. Set DATA to “1000 0000
4. Give XTAL1 a positive pulse. This loads the command.
5. Give WR a negative pulse. This starts the Chip Erase. RDY/BSY goes low.
6. Wait until RDY/BSY goes high before loading a new command.
1. Set XA1, XA0 to “1,0”. This enables command loading.
2. Set BS1 to “0”.
3. Set DATA to “0001 0000
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
