The HPS provides three GPIO interfaces that are based on Synopsys DesignWare APB* General Purpose Programming I/O peripheral and offer the following features:
  • Supports digital de-bounce
  • Configurable interrupt mode
  • Supports up to 17 dedicated 1.8 V and 3.0 V HPS I/O pins used for clock, reset, and external flash devices
  • Supports up to 48 shared 3.0 V I/O pins that can be used by either the HPS or the FPGA. These pins are useful for Ethernet, USB, and other communication functions
