A.
These HPI pins are muxed with the PCI peripheral. By default, these signals function as HPI. For more details on
these muxed pins, see the Device Configurations section of this data sheet.
B.
These PCI pins (excluding PCBE0 and XSP_CS) are muxed with the HPI or MDIO or GP0 peripherals. By default,
these signals function as HPI and no function, respectively. For more details on these muxed pins, see the Device
Configurations section of this data sheet.
C.
These HPI/PCI data pins (HD[31:16/AD[31:16]) are muxed with the EMAC peripheral. By default, these pins function
as HPI. For more details on the EMAC pin functions, see the Ethernet MAC (EMAC) peripheral signals section and
the terminal functions table portions of this data sheet.
