ROP (memory read-out protection register)
Bit 7-0:
ROP[7:0] memory read-out protection:
0xAA: enable read-out protection. When read-out protection is enabled, reading or
modifying the Flash program memory and DATA area in ICP mode (using the SWIM
interface) is forbidden, whatever the write protection settings are.
UBC (UBC user boot code reg.)
Bit 7-0:
UBC[7:0] user boot code write protection memory size:
0x00: no UBC, no Flash memory write-protection
0x01: pages 0 to 1 defined as UBC; 1 Kbyte memory write-protected (0x00.8000-
0x00.83FF)
0x02: pages 0 to 3 defined as UBC; 2 Kbyte memory write-protected (0x00.8000-
0x00.87FF)
0x03: pages 0 to 4 defined as UBC; 2.5 Kbyte memory write-protected (0x00.8000-
0x00.89FF)
...
0x3E: pages 0 to 63 defined as UBC; 32 Kbyte memory write-protected (0x00.8000-
