Port P data direction—
This bit determines whether the associated pin is an input or output.
The PWM forces the I/O state to be an output for an enabled channel. If the emergency shut-down feature is enabled
this pin is an input. In this case the data direction bit will not change.
1 Associated pin is configured as output
0 Associated pin is configured as input
Port P data direction—
This bit determines whether the associated pin is an input or output.
The PWM forces the I/O state to be an output for an enabled channel. In this case the data direction bit will not
change.
1 Associated pin is configured as output
0 Associated pin is configured as input
Port P reduced drive—Select reduced drive for output pin
This bit configures the drive strength of the associated output pin as either full or reduced. If a pin is used as input
this bit has no effect. The reduced drive function is independent of which function is being used on a particular pin.
1 Reduced drive selected (approx. 1/5 of the full drive strength)
0 Full drive strength enabled
