Description
ROP[7:0]: Memory readout protection (ROP)
0xAA: Enable readout protection (write access via SWIM protocol)
Note: Refer to the STM8A microcontroller family reference manual
(RM0016) section on Flash/EEPROM memory readout protection for
details.
UBC[7:0]: User boot code area
0x00: No UBC, no write-protection
0x01: Page 0 to 1 defined as UBC, memory write-protected
0x02: Page 0 to 3 defined as UBC, memory write-protected
0x03 to 0xFF: Pages 4 to 255 defined as UBC, memory write-protected
Note: Refer to the STM8A microcontroller family reference manual
(RM0016) section on Flash/EEPROM write protection for more details.
