      Hello!
      I'm hunting a strange bug. After some hours of flawless work our
      firmware hangs up. Via JTAG i saw, that in bank 0, the bootloader ROM
      (bank 9) is mapped. I thought this is only possible by setting pin
      BSEL1 to high and reset the MCU.
      Is there any undocumented register, that allows to switch bank9 to
      address 0?
