3.2.66.1
1 from 4 selection of the master value source
l
One master value source each can be connected to the inputs MSEL1−DFIN(1...4). For
selecting a master value source the assigned digital input MSEL1−EN−M(1...4) must be
triggered with a LOW−HIGH edge. An input set once remains active until another master value
source is selected.
l
If two or more inputs are selected at the same time, the input with the lowest selection number
is activated.
l
The selected input value is directly connected to the output MSEL1−OUT.
If no input has been selected (inputs MSEL1−EN−M(1...4) = LOW), 0 inc is output a the output

Locking the selection
A change−over to a new source is prevented by a HIGH level at the input MSEL1−LOCK. The input
channel last−output is locked until the input level at MSEL1−LOCK is reset to LOW.
