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.
