Upon clearing CCIF to launch the Program P-Flash command, the Memory Controller will program the
data words to the supplied global address and will then proceed to verify the data words read back as
expected. The CCIF flag will set after the Program P-Flash operation has completed.

17.4.5.6 Program Once Command
The Program Once command restricts programming to a reserved 64 byte field (8 phrases) in the
nonvolatile information register located in P-Flash. The Program Once reserved field can be read using the
Read Once command as described in Section 17.4.5.4. The Program Once command must only be issued
once since the nonvolatile information register in P-Flash cannot be erased. The Program Once command
must not be executed from the Flash block containing the Program Once reserved field to avoid code
runaway.
