Notes:

1. Not all instructions are applicable for all parts.

2. a = address.

3. Bits are programmed ‘0’, unprogrammed ‘1’.

4. To ensure future compatibility, unused Fuses and Lock bits should be unprogrammed (‘1’) .

5. Refer to the correspondig section for Fuse and Lock bits, Calibration and Signature bytes and

Page size.

6. See htt://www.atmel.com/avr for Application Notes regarding programming and programmers.

If the LSB in RDY/BSY data byte out is ‘1’, a programming operation is still pending. Wait until

this bit returns ‘0’ before the next instruction is carried out.

Within the same page, the low data byte must be loaded prior to the high data byte.

After data is loaded to the page buffer, program the EEPROM page, see Figure 20-8 on page

200.
