FC1
DeÞnes the FCC1 connection
0 FCC1 is not connected to the TSA and is either connected directly to the NMSIx pins or is not
used. The choice of general-purpose I/O port pins versus FCCn pins is made in the parallel I/O
control register.
1 FCC1 is connected to the TSA of the SIs. The NMSIx pins are available for other purposes.
