  1. STM32L4 has single 32-bit word with all needed options. I just works.
  2. STM32L1 is a bit more complicated. There are two 32-bit words to modify. Sometimes you need to change only one. When reprogramming a device with RDP level 1 you only have to change RDP to 0,
    everything else is erased. But even with RDP 0 you can't reflash large code while IWDG_SW is cleared. So I've decided to allow writing to 0x1ff80000 and 0x1ff80004.
