    16 3. The row n set/reset readback registers return the programmed relay state only if you use the module correctly. Since the driver power can be disabled (the power-on state), the row n set and row n reset registers can be written to and read from without moving any relay contacts. 4. When the mod...

    17 if the m-module is enabled to interrupt, it asserts the int line on the m-module interface to the carrier when the last commanded relay operation in the fifo has completed. For example, if relays in only one row were instructed to move, the module asserts an interrupt after that one row has been ...
