Hold keeps the BEC output at the state before the failsafe occurred.   Off
turns off the BEC, and On turns on the BEC.

The LED output will turn on when the BEC is enabled and turn off when the
BEC is disabled.  The LED can be a visual indicator for when the BEC is on
which is handy when using the BEC to drive a gas engine ignition.  Note that
during a system error condition (low voltage or failsafe occurred), the LED
will flash to indicate a problem has occurred.  The state of the BEC does not
affect the LED when a system error condition is detected.
