based interrupt events include End-of-Message, Selected mode
code, Format error, Subaddress control word interrupt, RT

rollover,
MT Command Stack rollover, RT Command Stack 50% rollover,
MT Data Stack 50% rollover, MT Command Stack 50% rollover,
and RT Circular buffer 50% rollover. Non-message interrupt
events/conditions include time tag rollover, RT address parity
error, RAM parity error, and BIT completed.
Bit 0 of the interrupt vector (interrupt status) word indicates
whether the entry is for a message interrupt event (if bit 0 is logic
"1") or a non-message interrupt event (if bit 0 is logic "0"). It is not
possible for one entry on the queue to indicate both a message
interrupt and a non-message interrupt.
As illustrated in FIGURE 10, for a message interrupt event, the
parameter word is a pointer. The pointer will reference the first
word of the RT or MT command stack descriptor (i.e., the Block
Status Word).
For a RAM Parity Error non-message interrupt, the parameter
will be the RAM address where the parity check failed. For the
RT address Parity Error, Protocol Self-test Complete, and Time
Tag rollover non-message interrupts, the parameter is not used;
it will have a value of 0000.
If enabled, an INTERRUPT STATUS QUEUE ROLLOVER inter-
rupt will be issued when the value of the queue pointer address
rolls over at a 64-word address boundary.
NOTE: Please see Appendix “F” of the Enhanced Mini-ACE
User’s Guide for important information applicable only to RT
MODE operation, enabling of the interrupt status queue and
use of specific non-message interrupts.
