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. Instructions accessing program memory use a word address. This word may be random within the page range.  
7. 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 27-8 on page  
302.
