You can access the port as a whole byte, or as individual bits - but there is no way to "bifurcate" it as you require.
You will have to read and write the port as a whole byte, and then use the normal shift & mask operations to separate & combine the two parts. BTW: wouldn't "bifurcate" imply an even split of 4 bits each...? |
