214 / 273 page ![]() 214 8042A–AVR–07/09 ATmega16HVB/32HVB 30.6.2 Serial Programming Instruction set Table 30-12 on page 214 and Figure 30-2 on page 215 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 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. Table 30-12.
