4 test pulse outputs that use different test pulses (test pulse0 (T0) ... test pulse3 (T3)) are
available for detecting shorts between the inputs.
Shorts between inputs are detected if the inputs are connected to different test pulses (test
pulse 0 ... test pulse 3).
Pulsing of test pulse outputs T0 ... T3 (typical times):
