The number of segment address lines is selected via PORT0 during reset. The selected
value can be read from bitfield SALSEL in register RP0H (read only) e.g. in order to
check the configuration during run time.
The table below summarizes the alternate functions of Port 4 depending on the number
of selected segment address lines (coded via bitfield SALSEL).
