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
