Programming the EEPROM
Figure 20-2. Addressing the Flash Which is Organized in Pages
Note:
Figure 20-3. Programming the Flash Waveforms
Note:
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):
3. Give XTAL1 a positive pulse. This loads the command, and the internal write signals
1. A: Load Command “0001 0001”.
2. G: Load Address High Byte (0x00 - 0xFF).
