3.6 Reset Control
There are two reset functionalities that are controlled by software: writing a “magic” value to the SOFTRES register
immediately triggers a reset of the whole board, and the BRKRES register controls how the “break” condition on the
tty0 port is monitored. Both reset functions generate a board reset with the exact same effect as if you had pressed the
reset button.
