A maximum of eight points can be used as a combination in a sequence. The program is activated or halted by an
occurrence of the previous event in each sequence.
Range Channels (Ch9 to Ch12):
The emulator has 4 range channels. The range channel can be defined as a combination of one or more of the
followings:
• An address or an address range
• Outside of an address range
• A read, a write, or either
• Data with a mask specification
• Bus state
• Area
• The value of four external probe signals
• The number of delay cycles after the event has occurred
5.7.4 Signals to Indicate Bus States and Areas
In the event detection system, signals indicating the MCU’s bus states and the accessed areas can be specified as
the event detection condition.
These signals are output from the MCU on the emulator; the signals to be acquired will vary according to the
emulator in use.
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).
For the trace function, refer to section 5.8, Viewing the Trace Information. For the hardware performance
function, refer to section 5.9, Analyzing Performance.
The following tables show examples of signals to indicate the bus states and areas that can be acquired by the
emulator.
