Signals to Indicate Bus States and Areas

The following tables show examples of signals to indicate the bus states and areas that can be acquired by the
emulator.

Note: The signals to indicate bus states and areas are used to set the [Bus/Area] condition of the event point.
They can also be acquired as the trace information. The bus state signals are also used to set the
condition not to acquire the trace ([Suppress] option) and in the Access Count Of Specified Range
Measurement mode for measuring the hardware performance ([Access Type] option).

Monitoring Function

This emulator incorporates the bus monitoring circuit as the standard, which thus allows a use of the monitoring
function to update the content of memory without affecting the realtime operation.
8.1.10

Trigger Points

This emulator incorporates the bus monitoring circuit as the standard, which thus allows a use of trigger points
that can be set on the [Trigger] sheet in the [Event] window.
