Self-diagnosis output pins. (See Table 2, Truth Table & Timing Chart.)
NPN transistor open-collector output. When output becomes
overcurrent, set to on; duty 97% on (low). At normal operation or at the
time of STOP, set to open (high).

Connects to the DC motor. Both the sink and the source have a current
capacity of 0.5 A. Features overcurrent detection function to temporarily
protect IC from instantaneous destruction at load short, ground fault, or
direct connection to high power. (See section on Multiple Detections
below.) Features diodes for absorbing counter electromotive force built
into both VCC and Gnd sides.

A motor is connected between this pin and the M (
+) pin. This pin has a
function equivalent to that of the M (
+) pin, and is controlled by input to
the DIA and DIB pins.
