When SELECT TYPE is “Average”
The block calculates the average of the valid inputs and transmits it to OUT. The number of inputs used to
calculate its value is indicated in SELECTED.

When SELECT TYPE is “Latched Good”
The valid input with the smaller input number is selected as an output and is held until it becomes invalid.
When it becomes invalid, the next valid input will be selected as an output regardless of the magnitude of the
value. Even if an input with the input number smaller than that of the currently selected input recovers, the
current selection is held.
Assuming that IN_2 is the valid input with the smallest input number, the order of input selection is IN_2 →
IN_3 → ...→ IN_8 → IN_1 → ....
If the power is turned OFF and then ON with SELECT TYPE set to “Latched Good,” input selection starts with
the IN that was selected before the power was turned OFF.
