Port S input data—
A read always returns the buffered input state of the associated pin. It can be used to detect overload or short circuit
conditions on output pins.
Port S data direction—
This bit determines whether the associated pin is an input or output.
1 Associated pin is configured as output
0 Associated pin is configured as input
Port S data direction—
This bit determines whether the associated pin is an input or output.
Depending on the configuration of the enabled SCI 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
