Chapter 28 256 Kbyte Flash Module (S12XFTX256K2V1)
MRDS bits are readable and writable while all remaining bits read 0 and are not writable in normal mode.
The WRALL bit is writable only in special mode to simplify mass erase and erase verify operations. When
writing to the FTSTMOD register in special mode, all unimplemented/reserved bits must be written to 0.
28.3.2.4
The FCNFG register enables the Flash interrupts and gates the security backdoor writes.

Margin Read Setting — The MRDS[1:0] bits are used to set the sense-amp margin level for reads of the Flash
array as shown in
Write to all Register Banks — If the WRALL bit is set, all banked FDATA registers sharing the same register
address will be written simultaneously during a register write.
0 Write only to the FDATA register bank selected using BKSEL.
1 Write to all FDATA register banks.
