Information

After the Program Section operation completes, the CCIF flag is set and normal access to
the FlexRAM is restored. The contents of the section program buffer may be changed by
the Program Section operation.

Command not available in current mode/security FSTAT[ACCERR]
An invalid flash address is supplied FSTAT[ACCERR]
Flash address is not phrase aligned FSTAT[ACCERR]
The requested section crosses a program flash sector boundary FSTAT[ACCERR]

The space required to store data for the requested number of phrases is more than half the

(FlexNVM devices)

28.4.12.8.1 Flash Sector Programming
The process of programming an entire flash sector using the Program Section command
is as follows:
1. If required, execute the Set FlexRAM Function command to make the FlexRAM
available as traditional RAM and initialize the FlexRAM to all ones.
2. Launch the Erase Flash Sector command to erase the flash sector to be programmed.
3. Beginning with the starting address of the programming acceleration RAM (program
flash only devices) or FlexRAM (FlexNVM devices), sequentially write enough data
to the RAM to fill an entire flash sector. This area of the RAM serves as the section
program buffer.
NOTE
In step 1, the section program buffer was initialized to all
ones, the erased state of the flash memory.
The section program buffer can be written to while the operation launched in step 2
is executing, i.e. while CCIF = 0.
4. Execute the Program Section command to program the contents of the section
program buffer into the selected flash sector.
5. If a flash sector is larger than half the FlexRAM, repeat steps 3 and 4 until the sector
is completely programmed.
6. To program additional flash sectors, repeat steps 2 through 4.
