PRELIMINARY

PU1

M0C0P



Function 1: Port U general purpose input or output pins.

Function 2: High current PWM output pins which can be used

for motor drive. These pins interface to the coils of motor 0.

PWM output on M0C0M results in a positive current flow

through coil 0 when M0C0P is driven to a logic high state.
