These bits are used to enable the device's IRQ sources into the SCI logic. The SCI logic output for
the IRQs is as follows:
SCI logic output = (URBSCIEN and URBSCISTS) or (URASCIEN and URASCISTS) or (FDCSCIEN
and FDCSCISTS) or (PRTSCIEN and PRTSCISTS) or (KBCSCIEN and KBCSCISTS) or
(MOUSCIEN and MOUSCISTS) or (IRSCIEN and IRSCISTS)
