Programming the EEPROM
2573G–AVR–07/09
Figure 112. Addressing the Flash Which is Organized in Pages
Note:
Figure 113. Programming the Flash Waveforms
Note:
The EEPROM is organized in pages, see Table 106 on page 249. When programming
the 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 “Programming the Flash” on page 252 for details on
Command, Address and Data loading):
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).
