Programming the EEPROM
Reading the Flash
The EEPROM is organized in pages, see
EEPROM, the program data is latched into a page buffer. This allows one page of data to be
programmed simultaneously. The programming algorithm for the EEPROM data memory is as
follows (refer to
Data loading):
K: Repeat 3 through 5 until the entire buffer is filled
L: Program EEPROM page
Figure 27-4. Programming the EEPROM Waveforms
The algorithm for reading the Flash memory is as follows (refer to
page 295
RESET +12V
1. A: Load Command “0001 0001”
2. G: Load Address High Byte (0x00 - 0xFF)
3. B: Load Address Low Byte (0x00 - 0xFF)
4. C: Load Data (0x00 - 0xFF)
5. E: Latch data (give PAGEL a positive pulse)
1. Set BS1 to “0”
2. Give WR a negative pulse. This starts programming of the EEPROM page. RDY/BSY
3. Wait until to RDY/BSY goes high before programming the next page (see
1. A: Load Command “0000 0010”
2. G: Load Address High Byte (0x00 - 0xFF)
3. B: Load Address Low Byte (0x00 - 0xFF)
4. Set OE to “0”, and BS1 to “0”. The Flash word low byte can now be read at DATA
5. Set BS1 to “1”. The Flash word high byte can now be read at DATA
6. Set OE to “1”
