This IC has two MUTE terminal (MU1 and MU2).
It is possible to control ON / OFF of each channel by external logic
inputs.
It has four kinds of function for select.In case of SELECT1, the bias
of all circuit becomes OFF.
Therefore, this mode is available in order to reduce the power
dissipation when the waiting mode.
In case of SELECT2,it is possible to select the PWM reverse
braking to take the brake of Spindle motor.

Also,in case of SELECT4,it is possible to select the short braking
when in the same.
In case of SELECT3,it is possible to do OFF the slide channel.
Regard with making OFF the loading channel in case of
SELECT2,SELECT3 and SELECT4,please refer to
[Loading channel].
