Current Sense Select (W) Base + 3
h
This register controls the current sense relays of the card.
Since only one current sense channel at a time per slot is
allowed, these channel selects are encoded. This allows for
either none or one current sense relay to be selected. Writing to
this register starts the reed relay timer.
