A more efficient data transfer can be achieved using the PROG_PAGELOAD instruction:
1. Enter JTAG instruction AVR_RESET and shift 1 in the Reset Register.
2. Enter instruction PROG_ENABLE and shift 1010_0011_0111_0000 in the Program-
1. Enter JTAG instruction PROG_COMMANDS.
2. Disable all programming instructions by using no operation instruction 11a.
3. Enter instruction PROG_ENABLE and shift 0000_0000_0000_0000 in the program-
4. Enter JTAG instruction AVR_RESET and shift 0 in the Reset Register.
