Page 26 - APPENDIX A: Interrupt Handling

25 APPENDIX A: Interrupt Handling A.2 Why Use an Interrupt Status Port (ISP)? The answer to the polling inefficiency was the Interrupt Status Port (ISP). The ISPis a read-only 8-bit register that sets a corresponding bit when an interrupt ispending. Port 1’s interrupt line corresponds with bit D0 of...
