There seem to be a problem with this flag now. As we have now a "discharge"
and a "clearevent" node in the DS2409 code, I'll just left out setting this
flag in the latter one to demonstrate the following:
janskiste:~ # tclsh
% package require ow ; OW::init /dev/i2c-1 ; OW::get uncached
bus.7/,bus.6/,bus.5/,bus.4/,bus.3/,bus.2/,bus.1/,bus.0/,29.A74101000000/,29.8F4101000000/,1F.141B05000000/,1F.0F1B05000000/,alarm/
% OW::get alarm
29.A74101000000/,29.8F4101000000/
--- Connect keys in both keylocks ---
% OW::get alarm
29.A74101000000/,29.8F4101000000/,1F.141B05000000/,1F.0F1B05000000/
% OW::put 1F.141B05000000/discharge 1
% OW::get alarm
29.A74101000000/,29.8F4101000000/
%
Huh? Both alarms were cleared?
--- Connect keys in both keylocks again ---
% OW::get alarm
29.A74101000000/,29.8F4101000000/,1F.141B05000000/,1F.0F1B05000000/
% OW::put 1F.141B05000000/clearevent 1
% OW::get alarm
29.A74101000000/,29.8F4101000000/,1F.0F1B05000000/
%
Ahh, that's better.
It seems to me the entire state of the DS2409 in the level directly *below*
the discharged line is invalidated, too.
Kind regards
