MxPWM held high results in drive-coast operation (vs. drive-brake when
the PWM is applied to MxPWM and D2 is held high). Toggling this pin
will clear any latched faults. Note that the disable lines from both drivers
are tied together. See
Section 6.b
for information on how to individually
access the disable pins (this is typically not necessary).
