Data Sheet
Interrupt type
The interrupt vectors are divided into four basic groups, where TYPE
determines the interrupt group. A further classification of interrupts is
done with the subtype indication.

Interrupt subtype
A specific interrupt type is divided into several subtypes. In general
STYPE(1) indicates the data path (transmit, receive) generating the
interrupt.
Interrupt queue
The interrupt vectors are written into 9 external interrupt queues located
in the shared memory. Corresponding to these 9 queues are 9 interrupt
queue start addresses and 8 interrupt queue length registers, since the
interrupt queue 8 has a fixed length of 2 x 256).
Interrupt Information
INT itself contains the interrupt information. The meaning of INT is
dependent on TYPE and STYPE indication.
