Bootloader
The low density value line STM8L05xxx ultra low power devices feature a built-in bootloader
(see UM0560: STM8 bootloader user manual).
The bootloader is used to download application software into the device memories,
including RAM, program and data memory, using standard serial interfaces. It is a
complementary solution to programming via the SWIM debugging interface.
