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.
The Erase Flash Page Buffer command is used to erase the Flash Page Buffer.
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.
1. Load the NVM CMD with the Erase Flash Page Buffer command.
2. Set the Command Execute bit (NVMEX) in the NVM Control Register A (NVM CTRLA).
This requires the timed CCP sequence during self-programming.
