[ Module] Interrupt and FIFO Status register
Addresses: 9000_0000 / 9000_8000 / 9001_0000 / 9001_8000 / 9002_0000 /
9002_8000 / 9003_0000 / 9003_8000
The Interrupt and FIFO Status register allows software to determine the cause of
the current low speed peripheral interrupts and to clear the interrupt bit.
Note:
An access type of R/W* means that the processor must write 1 to clear the
value if the read value is 1. If the read value is 0, the write value must be 0.
