I/O Memory Mapping Chapter 3
The bits are defined as follows:
• Shaded bit positions must be set to 0.
• Input filter: Real input point filter selection. See page 190
.
• EI_Ix: Enable input interrupt; 1 = interrupt enabled, 0 = interrupt
disabled.
• IT_Ix: Input interrupt type; 1 = generate interrupt on real input point
transition from on to off, 0 = generate interrupt on real input point
transition from off to on.
• PFE: Program to fault enable; 1 = fault value applied, 0 = program value
applied.
• PMx: Program mode; 1 = hold last state, 0 = user-defined safe state.
• PVx: Program value; 1 = output on, 0 = output off.
• FMx: Fault mode; 1 = hold last state, 0 = user-defined safe state.
• FVx: Fault value; 1 = output on, 0 = output off.
• DB_x: Output Control; 1 = output in Direct Control mode, 0 = output
in BOOLEAN Control mode.
