Programming the EEPROM
Figure 21-2. Addressing the Flash Which is Organized in Pages
Flash programming waveforms are illustrated in
letters refer to the programming steps described earlier.
Figure 21-3. Programming the Flash Waveforms
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 (see
data):
• A: Load Command “0001 0001”.
• G: Load Address High Byte (0x00 - 0xFF).
• B: Load Address Low Byte (0x00 - 0xFF).
