128 KByte Flash Module (S12XFTMR128K1V1)
During the reset sequence, the FOPT register is loaded from the Flash nonvolatile byte in the Flash
configuration field at global address 0x7F_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.
19.3.2.16 Flash Reserved2 Register (FRSV2)
This Flash register is reserved for factory testing.
All bits in the FRSV2 register read 0 and are not writable.
19.3.2.17 Flash Reserved3 Register (FRSV3)
This Flash register is reserved for factory testing.
All bits in the FRSV3 register read 0 and are not writable.
19.3.2.18 Flash Reserved4 Register (FRSV4)
This Flash register is reserved for factory testing.
