摘要：
An I/O port interrupt mechanism includes a source register connected to the port for reporting sources of interrupts arising within the port, an interrupt mask register connected to the source register and operable to configure the I/O port for generation of interrupts, and an interrupt controller connected to the output of the source register and operable to hold off interrupts arising within the I/O port.
