3.2.2. Parallel I/O Core

The Parallel I/O (PIO) modules provide general input/output (I/O) access from the Avalon® master (JTAG to Avalon® master bridge). There are two sets of 32-bit PIO registers:

  • Status registers—input from the HDL components to the Avalon® master
  • Control registers—output from the Avalon® master to the HDL components

The registers are assigned in the top level HDL file (io_status for status registers, io_control for control registers). The tables below describe the signal connectivity for the status and control registers.
