for motor drive. These pins interface to the coils of motor 1.
PWM output on M1C1M results in a positive current flow
through coil 1 when M1C1P is driven to a logic high state.
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 1.
PWM output on M1C0M results in a positive current flow
through coil 0 when M1C0P is driven to a logic high state.
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 M0C1M results in a positive current flow
through coil 1 when M0C1P is driven to a logic high state.
