RT COMMAND ILLEGALIZATION
The Enhanced Mini-ACE provides an internal mechanism for RT
Command Word illegalizing. By means of a 256-word area in
shared RAM, the host processor may designate that any mes-
sage be illegalized, based on the command word T/R bit, sub-
address, and word count/mode code fields. The Enhanced Mini-
ACE illegalization scheme provides the maximum in flexibility,
allowing any subset of the 4096 possible combinations of broad-
cast/own address, T/R bit, subaddress, and word count/mode
code to be illegalized.
The address map of the Enhanced Mini-ACE's illegalizing table
is illustrated in TABLE 41.

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.
