Erase & Write Application Section / Boot Loader Section Page
The Erase Application Section Page Erase and Erase Boot Loader Section Page commands are
used to erase one page in the Application Section or Boot Loader Section.
The BUSY flag in the NVM STATUS register will be set until the erase operation is finished. The
FBUSY flag is set as long the Flash is Busy, and the Application section cannot be accessed.
The Write Application Section Page and Write Boot Loader Section Page commands are used to
write the Flash Page Buffer into one flash page in the Application Section or Boot Loader
Section.
The BUSY flag in the NVM STATUS register will be set until the write operation is finished. The
FBUSY flag is set as long the Flash is Busy, and the Application section cannot be accessed.
An invalid page address in the Z-pointer will abort the NVM command. The Erase Application
Section Page command requires that the Z-pointer addresses the Application section, and the
Erase Boot Section Page command requires that the Z-pointer addresses the Boot Loader
Section.
The Erase & Write Application Section Page and Erase & Write Boot Loader Section Page com-
mands are used to erase one flash page and then write the Flash Page Buffer into that flash
page in the Application Section or Boot Loader Section, in one atomic operation.
The BUSY flag in the NVM STATUS register will be set until the operation is finished. The
FBUSY flag is set as long the Flash is Busy, and the Application section cannot be accessed.
An invalid page address in the Z-pointer will abort the NVM command. The Erase & Write Appli-
cation Section command requires that the Z-pointer addresses the Application section, and the
Erase & Write Boot Section Page command requires that the Z-pointer addresses the Boot
Loader Section.
