Interrupts from Port C
The port C lines associated with CDx and CTSx have a mode of operation where the pin can be internally
connected to the SCC/FCC but can also generate interrupts. Port C still detects changes on the CTS and
CD pins and asserts the corresponding interrupt request, but the SCC/FCC simultaneously uses CTS
