6.3.1
The CFM configuration field comprises 24 bytes of reserved array memory space that determines the
module protection and access restrictions out of reset. Data to secure the Flash from unauthorized access
is also stored in the CFM configuration field.
6.3.2
The configuration information in the Flash base address register (FLASHBAR) controls the operation of
the Flash module.
The FLASHBAR register contains several control fields. These fields are shown in

The FLASHBAR holds the base address of the Flash. The MOVEC instruction provides write-only
access to this register.
The FLASHBAR can be read or written from the debug module in a similar manner.
All undefined bits in the register are reserved. These bits are ignored during writes to the
FLASHBAR, and return zeroes when read from the debug module.
The back door enable bit, FLASHBAR[BDE], is cleared at reset, disabling back door access to the
Flash.
The FLASHBAR valid bit is programmed according to the chip mode selected at reset (see

The default value of the FLASHBAR is determined by the chip
configuration selected at reset (see

the FLASHBAR located in the processor’s CPU space will be invalid and it
must be initialized with the valid bit set before the CPU (or modules) can
access the on-chip Flash.
