1. The Flash Range CRC command used byte addressing of the Flash.
2. Will depend on the flash section (Application or Boot Loader) that is actually addressed.
3. This command is qualified with the Lock Bits, and requires that the Boot Lock Bits are unprogrammed.
4. When using a command that changes the normal behavior of the LPM command; READ_USER_SIG_ROW and

Flash Self-Programming Commands
The (E)LPM instruction is used to read one byte from the Flash memory.
The destination register will be loaded during the execution of the LPM instruction.

1. Load the Z-pointer with the byte address to read.
2. Load the NVM Command register (NVM CMD) with the No Operation command.
3. Execute the LPM instruction.
