WORD MONITOR MODE
In the Word Monitor Terminal mode, the PCI Mini-ACE
Mark3/Micro-ACE TE monitors both 1553 buses. After the soft-
ware initialization and Monitor Start sequences, the PCI Mini-
ACE Mark3/Micro-ACE TE stores all Command, Status, and
Data Words received from both buses. For each word received
from either bus, a pair of words is stored to the PCI Mini-ACE
Mark3/Micro-ACE TE's shared RAM. The first word is the word
received from the 1553 bus. The second word is the Monitor
Identification (ID), or "Tag" word. The ID word contains informa-
tion relating to bus channel, word validity, and inter-word time
gaps. The data and ID words are stored in a circular buffer in the
shared RAM address space.
WORD MONITOR MEMORY MAP
A typical word monitor memory map is illustrated in TABLE 59.
TABLE 59 assumes a 64K address space for the PCI Mini-ACE
Mark3/Micro-ACE TE's monitor. The Active Area Stack pointer
provides the address where the first monitored word is stored. In
the example, it is assumed that the Active Area Stack Pointer for
Area A (location 0100) is initialized to 0000. The first received
data word is stored in location 0000, the ID word for the first word
is stored in location 0001, etc.
The current Monitor address is maintained by means of a
counter register. This value may be read by the CPU by means
of the Data Stack Address Register. It is important to note that
when the counter reaches the Stack Pointer address of 0100 or
0104, the initial pointer value stored in this shared RAM location
will be overwritten by the monitored data and ID Words. When
the internal counter reaches an address of FFFF (or 0FFF, for an
PCI Mini-ACE Mark3/Micro-ACE TE with 4K RAM), the counter
rolls over to 0000.
WORD MONITOR TRIGGER
In the Word Monitor mode, there is a pattern recognition trigger
and a pattern recognition interrupt. The 16-bit compare word for
both the trigger and the interrupt is stored in the Monitor Trigger
Word Register. The pattern recognition interrupt is enabled by set-
ting the MT Pattern Trigger bit in Interrupt Mask Register. The pat-
tern recognition trigger is enabled by setting the Trigger Enable bit
in Configuration Register #1 and selecting either the Start-on-trig-
ger or the Stop-on-trigger bit in Configuration Register #1. The
Word Monitor may also be started by means of a low-to-high
transition on the EXT_TRIG input signal.
SELECTIVE MESSAGE MONITOR MODE
The PCI Mini-ACE Mark3/Micro-ACE TE Selective Message
Monitor provides monitoring of 1553 messages with filtering based
on RT address, T/R bit, and subaddress with no host processor
intervention. By autonomously distinguishing between 1553 com-
mand and status words, the Message Monitor determines when
messages begin and end, and stores the messages into RAM,
based on a programmable filter of RT address, T/R bit, and sub-
address.
The selective monitor may be configured as just a monitor, or as a
combined RT/Monitor. In the combined RT/Monitor mode, the
PCI Mini-ACE Mark3/Micro-ACE TE functions as an RT for one
RT address (including broadcast messages), and as a selective
message monitor for the other 30 RT addresses. The PCI Mini-
ACE Mark3/Micro-ACE TE Message Monitor contains two stacks,
a command stack and a data stack, that are independent from the
