to a logic high state. PWM output on M2C1M results in a positive current flow through coil 1 when
M2C1P is driven to a logic high state.

M3C0M/M3C0P/M3C1M/M3C1P — PWM Output Pins for Motor 3
High current PWM output pins that can be used for motor drive. These pins interface to the coils of
motor 3. PWM output on M3C0M results in a positive current flow through coil 0 when M3C0P is driven
to a logic high state. PWM output on M3C1M results in a positive current flow through coil 1 when
M3C1P is driven to a logic high state.
