Programming the
EEPROM
2513K–AVR–07/09
Figure 98. 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):
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).
K: Repeat 3 through 5 until the entire buffer is filled.
L: Program EEPROM page
1. Set BS 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
goes low.
(See
RESET +12V
“XX” is don’t care. The letters refer to the programming description above.
