256 KByte Flash Module (S12XFTMR256K1V1)
The security function in the Flash module is described in
18.3.2.3
The FCCOBIX register is used to index the FCCOB register for Flash memory operations.
CCOBIX bits are readable and writable while remaining bits read 0 and are not writable.
18.3.2.4
The FECCRIX register is used to index the FECCR register for ECC fault reporting.
ECCRIX bits are readable and writable while remaining bits read 0 and are not writable.
