5.15.4. I/O Pin Multiplexing System Integration

The HPS I/O block consists of the following sub-blocks:

  • Dedicated pin multiplexers (muxes): Muxes for the dedicated I/O bank
  • FPGA access pin multiplexers: Muxes for HPS peripheral connections to the FPGA fabric
  • Register target interface: Provides access to control registers, which allow the bootloader to initialize I/O pins and HPS peripheral interfaces at system startup
