8.5.2
The FMIBDR register holds the 16-bit data for read or write
access to an information block. The FMIBDR register is
cleared after device reset. The CPU bus master has read/
write access to this register.
IBD
8.5.3
The FM0WER register controls section-level write protec-
tion for the first half of the flash program memory. The
FMS0WER registers controls section-level write protection
for the flash data memory. Each data block is divided into 16
8K-byte sections. Each bit in the FM0WER and FSM0WER
registers controls write protection for one of these sections.
The FM0WER and FSM0WER registers are cleared after
device reset, so the flash memory is write protected after re-
set. The CPU bus master has read/write access to this reg-
isters.

Flash Memory Information Block Data Register
(FMIBDR/FSMIBDR)
Flash Memory 0 Write Enable Register
(FM0WER/FSM0WER)
The Information Block Data field holds the
data word for access to an information block.
For write operations the IBD field holds the
data word to be programmed into the informa-
tion block location specified by the IBA ad-
dress. During a read operation from an
information block, the IBD field receives the
data word read from the location specified by
the IBA address.
The Flash Memory 0 Write Enable n bits con-
trol write protection for a section of a flash
memory data block. The address mapping of
the register bits is shown below.

8.5.4
The FM1WER register controls write protection for the sec-
ond half of the program flash memory. The data block is di-
vided into 16 8K-byte sections. Each bit in the FM1WER
register controls write protection for one of these sections.
The FM1WER register is cleared after device reset, so the
flash memory is write protected after reset. The CPU bus
master has read/write access to this registers.

8.5.5
The FSM0WER register controls write protection for the
flash data memory. The data block is divided into 16 512-
byte sections. Each bit in the FSM0WER register controls
write protection for one of these sections. The FSM0WER
register is cleared after device reset, so the flash memory is
write protected after reset. The CPU bus master has read/
write access to this registers.
