The Controller Status Register can be polled at any time to see if there is a pending fault
condition. Any one bit set will cause the controller to turn off the Power Output stage. Con-
ditions marked as Temporary mean that the controller will resume operation as soon as the
fault condition disappears. Permanent conditions will cause the controller to remain off
until it is reset either by cycling power, pressing the reset button, or sending the %rrrrrr
command.
