Port U input data—
This register always reads back the buffered state of the associated pins. This can also be used to detect overload
or short circuit conditions on output pins.
Port U data direction—
If enabled the Motor driver PWM output it will force the I/O state to be output.
1 Associated pin is configured as output.
0 Associated pin is configured as input.
Port U data direction—
If enabled the Motor driver PWM output it will force the I/O state to be output.
Else if corresponding TIM0 output compare channel is enabled, it will be force as output
1 Associated pin is configured as output.
0 Associated pin is configured as input.
