The bit that is ”1” shows the cause of the interrupt. When evaluating the interrupt request bytes,
note that several bits may be ”1”.
Direction bit RICH has been included in the interrupt request bytes. This bit mirrors the current
state of the RICH bit in the status area. It does not relate to the state of this bit when the interrupt
occurred.
Interrupt bit Bit is ”1”
