These bits enable the generation of an SMI interrupt due to any IRQ of the devices. These 4 bits
control the printer port, FDC, UART A, and UART B SMI logics respectively. The SMI logic output for
the IRQs is as follows:
SMI logic output = (URBIRQEN and URBIRQSTS) or (URAIRQEN and URAIRQSTS) or (FDCIRQEN
and FDCIRQSTS) or (PRTIRQEN and PRTIRQSTS) or (KBCIRQEN and KBCIRQSTS) or
(MOUIRQEN and MOUIRQSTS) or (IRIRQEN and IRIRQSTS)
