FPLDIS
Flash Protection Lower address range Disable — The FPLDIS bit determines whether there is a
protected/unprotected area in the lower address space of the Flash block.
0 Protection/Unprotection enabled
1 Protection/Unprotection disabled
1:0
Flash Protection Lower Address Size — The FPLS[1:0] bits determine the size of the protected/unprotected
FPLS[1:0] area as shown in Table 2-12. The FPLS[1:0] bits can only be written to while the FPLDIS bit is set.
