Description
OPT0
ROP[7:0]: Memory readout protection (ROP)
AAh: Enable readout protection (write access via SWIM protocol)
Note: Refer to the STM8A microcontroller family reference manual
(RM0009) section on Flash/EEPROM memory readout protection for
details.
OPT1
UBC[7:0]: User boot code area
00h: No UBC, no write-protection
01h: Page 0 to 1 defined as UBC, memory write-protected
02h: Page 0 to 3 defined as UBC, memory write-protected
03h to FFh: Pages 4 to 255 defined as UBC, memory write-protected
Note: Refer to the STM8A microcontroller family reference manual
(RM0009) section on Flash/EEPROM write protection for more details.

AFR7: Alternate function remapping option 7
0: Port D4 alternate function = TIM2_CC1
1: Port D4 alternate function = BEEP
AFR6: Alternate function remapping option 6
0: Port B5 alternate function = AIN5, port B4 alternate function = AIN4
1: Port B5 alternate function = I2C_SDA, port B4 alternate function =
I2C_SCL.
AFR5: Alternate function remapping option 5
0: Port B3 alternate function = AIN3, port B2 alternate function = AIN2,
port B1 alternate function = AIN1, port B0 alternate function = AIN0.
1: Port B3 alternate function = TIM1_ETR, port B2 alternate function =
TIM1_NCC3, port B1 alternate function = TIM1_NCC2, port B0 alternate
function = TIM1_NCC1.
