pri: a prioritized list of inputs, used
when change-over is automatic. The
list can have 1, 2 or 3 entries, or
levels. Manual mode is effectively the
same as automatic mode with one
priority level only, but has its own
command.
0 = from electrical input
1 = from optical input
t1 and t2: change-over doesn't
happen immediately, as a precaution
against glitches and unstable signals.
The timers t1 and t2 let the user
decide how long (in ms) we will cling
on to a missing input before we
consider it gone and move on to the
next pri level, and how long an input
with a higher priority should be
present before we consider it
repaired and switch back,
respectively.
