A.These HPI pins are muxed with the PCI peripheral. By default, these pins function as HPI. When the HPI is enabled, the number of HPI pins used depends on the HPI configuration (HPI16 or HPI32). For more details on these muxed pins, see the Device Configuration section of this document.

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 Configuration section of this document.
