Chapter 2 256 Kbyte Flash Module (FTS256K2V1)
FPROT register reflect the active protection scenario. See the FPHS and FPLS descriptions for additional
restrictions.
2.3.2.7
The banked FSTAT register defines the operational status of the module.
CBEIF, PVIOL, and ACCERR are readable and writable, CCIF and BLANK are readable and not writable,
remaining bits read 0and are not writable in normal mode. FAIL is readable and writable in special mode.
FAIL must be clear when starting a command write sequence.
