A. These HPI pins are muxed with the PCI peripheral. By default, these pins function as HPI and no function, respectively. For more details on
these muxed pins, see the Device Configurations section of this data sheet.
B. These McBSP1 peripheral pins are muxed with the GPIO peripheral pins and by default these signals function as GPIO peripheral pins. For
more details, see the Device Configurations section of this data sheet.
