Description

OPTBL

BL[7:0] Bootloader option byte

For STM8S products, this option is checked by the boot ROM code

after reset. Depending on the content of addresses 0x487E, 0x487F,

and 0x8000 (reset vector), the CPU jumps to the bootloader or to

the reset vector. Refer to the UM0560 (STM8L/S bootloader manual)

for more details.

For STM8L products, the bootloader option bytes are on addresses

0xXXXX and 0xXXXX+1 (2 bytes). These option bytes control

whether the bootloader is active or not. For more details, refer to the

UM0560 (STM8L/S bootloader manual) for more details.
