Process output data of approved SWIRE slaves (except SWIRE-DIL)
The field output data of all approved SWIRE slaves apart from SWIRE-DIL is passed
to the process output data.
Meaning of the 4-bit process output data of approved SWIRE-DIL slaves apart from
SWIRE-DIL devices:
Tab. 12 Process output data of approved SWIRE slaves (except SWIRE-DIL)
If a slave does not support the number of 4 output bits, the outputs are assigned to
the process output data in ascending order, likewise starting from the least signifi-
cant bit.
