27.33.1 Flash Status Register (FTFA_FSTAT)
The FSTAT register reports the operational status of the flash memory module.
The CCIF, RDCOLERR, ACCERR, and FPVIOL bits are readable and writable. The
MGSTAT0 bit is read only. The unassigned bits read 0 and are not writable.
NOTE
When set, the Access Error (ACCERR) and Flash Protection
Violation (FPVIOL) bits in this register prevent the launch of
any more commands until the flag is cleared (by writing a one
to it).

CCIF
Command Complete Interrupt Flag
Description
The CCIF flag indicates that a flash command has completed. The CCIF flag is cleared by writing a 1 to
CCIF to launch a command, and CCIF stays low until command completion or command violation.
The CCIF bit is reset to 0 but is set to 1 by the memory controller at the end of the reset initialization
sequence. Depending on how quickly the read occurs after reset release, the user may or may not see the
0 hardware reset value.
