The BUSY flag in the NVM STATUS register will be set until the operation is finished.
The Write Application Section Page, Write Boot Loader Section Page, Write User Signature Row
and Write EEPROM Page is used to write a loaded Flash/EEPROM page buffer into the
selected memory space
The BUSY flag in the NVM STATUS register will be set until the operation is finished.
The Erase & Write Application Section Page, Erase & Write Boot Loader Section Page, and
Erase & Write EEPROM Page is used to erase one page and then write a loaded
Flash/EEPROM page buffer into that page in the selected memory space, in one atomic
operation.
The BUSY flag in the NVM STATUS register will be set until the operation is finished.
The Erase Application Section, Erase Boot Loader Section and Erase EEPROM Section com-
mand is used to erase the complete section selected.
The BUSY flag in the NVM STATUS register will be set until the operation is finished.
The Write Fuse and Write Lock Bit command is used to write the fuses and the lock bits to a
more secure setting.
The BUSY flag in the NVM STATUS register will be set until the command is finished.
For lock bit write the LOCK BIT write command can also be used.
