2.2.10. Hard Processor System I/O Pin Multiplexing

The SoC has a total of 48 flexible I/O pins that are used for hard processor system (HPS) operation, external flash memories, and external peripheral communication. All of the 48 HPS I/O pins can also act as loaner I/O from the FPGA fabric. A pin multiplexing mechanism allows the SoC to use the flexible I/O pins in a wide range of configurations.
