312 / 393 page  312 8018N–AVR–08/09 ATmega169P 27.8.3 Serial Programming Instruction set Table 27-16 and Figure 27-12 on page 313 describes the Instruction set. 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 corresponding section for Fuse and Lock bits, Calibration and Signature bytes and Page size. 6. Instructions accessing program memory use a word address. This address 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. Table 27-16.
