21.3.2.16 Flash Option Register (FOPT)
The FOPT register is the Flash option register.
1
All bits in the FOPT register are readable but are not writable.
During the reset sequence, the FOPT register is loaded from the Flash nonvolatile byte in the Flash
configuration field at global address 0x3_FF0E located in P-Flash memory (see
by reset condition F in
containing the Flash nonvolatile byte during the reset sequence, all bits in the FOPT register will be set.
21.3.2.17 Flash Reserved5 Register (FRSV5)
This Flash register is reserved for factory testing.
All bits in the FRSV5 register read 0 and are not writable.
21.3.2.18 Flash Reserved6 Register (FRSV6)
This Flash register is reserved for factory testing.
