The program operation will program a previously erased address in the flash memory using an embedded
algorithm.
An example flow to execute the program operation is shown in
sequence is as follows:
If an address to be programmed is in a protected area of the flash block, the FPVIOL flag in the FSTAT
register will set and the program command will not launch. Once the program command has successfully
launched, the FCCF flag in the FSTAT register will set after the program operation has completed.

1. Write to an aligned flash block address to start the command write sequence for the program
2. Write the program command, 0x20, to the FCMD register.
3. Clear the FCBEF flag in the FSTAT register by writing a 1 to FCBEF to launch the program
command. The data written will be programmed to the address written.
