NVM Flash Commands
Figure 30-2. Flash addressing for self-programming
The NVM commands that can be used for accessing the Flash Program Memory, Signature
Row and Calibration Row are listed in
For self-programming of the Flash, the Trigger for Action Triggered Commands is to set the
CMDEX bit in the NVM CTRLA register (CMDEX). The Read Triggered Commands are trig-
gered by executing the (E)LPM instruction (LPM). The Write Triggered Commands is triggered
by a executing the SPM instruction (SPM).
The Change Protected column indicate if the trigger is protected by the Configuration Change
Protection (CCP). This is a special sequence to write/execute the trigger during self-program-
ming, for more details refer to
CCP is not required for external programming. The two last columns shows the address pointer
used for addressing, and the source/destination data register.
