   commands we want to send from the computer to the programmer:

   computer -> nRF message types

   • send a byte over UART to SCuM
   • loading new SCuM binary from the computer into the RAM memory of the nRF (64kB); there is 256 kB of RAM in the nRF52840
   • trigger a 3wb bootload sequence

   nRF -> computer message types

   • received a byte over UART from SCuM
   • operation completed
