Braking
When the BRAKE pin is pulled below 1.4V, the low side
output drivers LA, LB, and LC are turned on and the high
side output drivers HA, HB, HC are turned off. Braking
causes rapid deceleration of the motor and current limiting is
de-activated, and care should be taken when using the
BRAKE pin. BRAKE is has an internal 4kΩ pull-up as
shown in Figure 10, and can be driven by a switch to ground,
an open collector or drain logic signal, or a TTL logic signal.
