Table 11-3 shows the generic flash command format. The high byte of the first word in
the CCOB array contains the command code, followed by the parameters for this specific
flash command. For details on the FCCOB settings required by each command, see the
flash command descriptions in
Table 11-3. FCCOB – flash command mode typical usage

The contents of the FCCOB parameter fields are transferred to the memory controller
when the user clears the FSTAT[CCIF] command completion flag by writing 1. The
CCIF flag will remain clear until the flash command has completed. Upon completion,
the memory controller will return FSTAT[CCIF] to 1 and the FCCOB register will be
used to communicate any results.
The following table presents the valid flash commands, as enabled by the combination of
the functional MCU mode with the MCU security state of unsecured or secured.
MCU secured state is selected by FSEC[SEC].
