    Programming Programming in an OS other than Windows I/O Port Input/Output Procedure Of 256 I/O port addresses assigned from the PC to BUS-PCI(PCI) boards, 248 ports are used for general-purpose accessing and the remaining 8 ports are used to control signals on the I/O expansion unit. With the control port of the BUS-PCI(PCI) board, you can specify the value of the eight highest bits of an address used for accessing the I/O expansion unit and enable or disable the I/O wait and the refresh signal.

  • Page 83: Interrupt Procedure

    Programming Interrupt Procedure One interrupt request level is assigned from the PC to the BUS-PCI(PCI) board. For this reason, the BUF-PCI(PCI) board detects multiple interrupt request signals generated on the I/O expansion unit one by one. If there is even just one interrupt request, the interrupt request signal is output to the PCI bus to request the PC for interrupt.
  • Page 84 Programming (6) Next, process the interrupt as necessary, implement the termination process on the interrupt controller of the PC, and exit the interrupt handler. (7) After all interrupt processes are finished, mask all interrupt request mask registers in the main routine and undo the PC settings as they were.
