After the Program Section operation completes, the CCIF flag is set. The contents of the
section program buffer may be changed by the Program Section operation.

28.4.10.8.1 Flash Sector Programming
The process of programming an entire flash sector using the Program Section command
is as follows:
1. Launch the Erase Flash Sector command to erase the flash sector to be programmed.
2. Beginning with the starting address of the programming acceleration RAM,
sequentially write enough data to the RAM to fill an entire flash sector. This area of
the RAM serves as the section program buffer. The section program buffer can be
written to while the operation launched in step 1 is executing, i.e. while CCIF = 0.
3. Execute the Program Section command to program the contents of the section
program buffer into the selected flash sector.
4. To program additional flash sectors, repeat steps 1 through 3.
28.4.10.9 Read 1s All Blocks Command
The Read 1s All Blocks command checks if the program flash blocks have been erased to
the specified read margin level, if applicable, and releases security if the readout passes,
i.e. all data reads as '1'.
