5 Reset infrastructure

5.1 MCU

The primary user reset for the MCU is the reset button on the MCU board. This will only reset the MCU.
It can also be reset using the board controller, by writing to the RESET_MCU bit in the RESET register.
Finally, it can be reset by debuggers.

5.2 Board controller

The board controller can be reset by pushing the reset button on the main board.
