0 = upper lines
0 = upper lines
1 = lower lines
1 = lower lines
Case 1: OFIDC[90h[6]] = 0; scaler input field ID as output ID; back-end interprets output field ID at logic 0
as upper output lines.
Case 2: OFIDC[90h[6]] = 1; task status bit as output ID; back-end interprets output field ID at logic 0 as
upper output lines.
Case 3: OFIDC[90h[6]] = 1; task status bit as output ID; back-end interprets output field ID at logic 1 as
upper output lines.
