Alarm acknowledgement
Alarm status #16 .. #1
The alarm acknowledgements are summarised in
a register as a coded alarm field. (Alarm #16 ->
0x8000, Alarm #1 -> 0x0001).
If a zero is written in the corresponding position
the active alarm is acknowledged. If the register is
written '0000' all the alarms are acknowledged.
