Port M data direction—
This bit determines whether the associated pin is an input or output.
Depending on the configuration of the enabled SPI the I/O state will be forced to be input or output. 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 M data direction—
This bit determines whether the associated pin is an input or output.
The enabled CAN forces the I/O state to be an output. 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 M data direction—
This bit determines whether the associated pin is an input or output.
The enabled CAN forces the I/O state to be 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 M 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
