The S/UNI-MPH is configured to select the J2 receive interface. The
connections between the two devices should be made as shown in the
"OPERATIONS - Using the JT2F" section. The register bits RDNINV and RFALL
are set to logic 1 so that ROH[x] is active low and so RDD[x] and ROH[x] are
sampled on the falling edge of RCLKI[x].
