Application Section / Boot Loader Section Page Write
The BUSY flag in the NVM STATUS register will be set, and the CPU is halted during the execu-
tion of the command.
The CRC checksum will be available in the NVM DATA register.
In order to use the Flash Range CRC all the Boot Lock Bits must be unprogrammed (no locks).
The command execution will be aborted if the Boot Lock Bits for an accessed location are set.
The Erase Application command is used to erase the complete Application Section.
The BUSY flag in the STATUS register will be set until the operation is finished. The CPU will be
halted during the complete execution of the command.
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.
