2.3.2.3
All 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.
Freescale Semiconductor
The unbanked FTSTMOD register is used to control Flash test features.

Write to All Register Banks — If the WRALL bit is set, all banked registers sharing the same register address
will be written simultaneously during a register write.
0 Write only to the bank selected via BKSEL.
1 Write to all register banks.
