Infrared Serial Communications Interface Module (IRSCI)
12.2 Pin Name Conventions
The generic names of the IRSCI I/O pins are:
IRSCI I/O (input/output) lines are implemented by sharing parallel I/O port pins. The full name of an IRSCI
input or output reflects the name of the shared port pin.
names of the IRSCI I/O pins. The generic pin names appear in the text of this section.
