No, you can't use PWM outputs that swing from about ~10v-~4v for *digital*
output. However, you can pull the 74HC374 (see motor output schematic) out
of socket and put a 16pin ribbon cable(rat shack) in the socket. Then take
the other
end to a protoboard and wire it up to the 74HC374 again. Now take the
output of the 374 as digital outputs. If you use the motor functions you
lose four outputs that are PWM (the cs pins) 5Q,6Q,7Q,&8Q.
