Chapter 24 128 KByte Flash Module (S12XFTM128K2V1)

The security function in the Flash module is described in

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.

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.

Offset Module Base + 0x0002

Offset Module Base + 0x0003

Flash CCOB Index Register (FCCOBIX)

Flash ECCR Index Register (FECCRIX)

Common Command Register Index— The CCOBIX bits are used to select which word of the FCCOB register

array is being read or written to. See

for more details.

= Unimplemented or Reserved

1. Preferred SEC state to set MCU to secured state.
