Notes:
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.
(1)
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
6. See htt://www.atmel.com/avr for Application Notes regarding programming and programmers.
