Triggering the Analyzer by Data
You may want to trigger the emulation analyzer when specific data
appears on the data bus. You can accomplish this by specifying "Data"
in the "Find State" field of analysis specification display.
There are some points to be noticed when you trigger the analyzer in
this way. You always need to specify the "Data" with 16 bits value
even when access to the data is performed by byte access. This is
because the analyzer is designed so that it can capture data on internal
data bus (which has 16 bits width). The following table shows the
way to specify the trigger condition by data.
(DATA READ/WRITE)
=====================================================
|
| Available
Location of data | Accesses | <DATA> Specification
=====================================================
Internal ROM,RAM | Word
| HHLL *1
+----------+---------------------
| Byte
| DDxx *2
-------------------+----------+---------------------
Others
| DDxx
=====================================================
(INSTRUCTION FETCH)
=====================================================
|
| Available
Location of data | Address | <DATA> Specification
=====================================================
Internal ROM,RAM | EVEN
| HHLL *1
+----------+---------------------
| ODD
| xxDD *2
--------------------+----------+---------------------
Others
| DDxx *2
=====================================================
*1 HHLL means 16 bits data
*2 DD means 8 bits data
For example, to trigger the analyzer when the processor performs word
access to data 1234 hex in internal ROM, you can use 1234h as the
"Data" specification.
To trigger the analyzer when the processor accesses data 12 hex in
external ROM, you can use 12xxh as "Data" specification.
