Address: 0x00d0_0010 and 0x00d0_0011
The banked registers are described in this subsection.
The SGFM Protection Register (SGFMPROT) is banked and specifies
which FLASH logical sectors are protected from program and erase
operations.
The SGFMPROT register is always readable and only writable when
LOCK = 0. To change which logical sectors are protected on a
temporary basis, write SGFMPROT with a new value after the LOCK bit
in SGFMCR has been cleared. To change the value of SGFMPROT that
will be loaded on reset, the protection byte in the FLASH configuration
field must be reprogrammed for the interleaved FLASH physical blocks
currently selected by BKSEL[1:0]. If necessary, the logical sector
containing the FLASH configuration field must be temporarily
unprotected using the method just described before reprogramming the
protection bytes.

Each FLASH logical sector can be protected from program and erase
