stored, and the stopping condition.
Screen display
Click the button on the Circuit Trace Option screen.
Operating procedure
1. Set the items on the screen.
2. Click the button.
The following message is displayed.

Item Description
Circuit Trace Data Storage Area Setting -
Start Address
Set the starting address of the monitor buffer area to which the trace data
are stored.
Size
Set the size of the monitor buffer area to which the trace data are stored.
Set the maximum address
*1
for the trace data storage space in the range
between 2602
H to 3FFFH (C02H to 1AFFH for the user-specified area). Note
that the range of this value is checked at start of the circuit trace when using
the user-specified area.
Stop Setting -
Stop by occurrence of timer 0 time-
out error
Check this to stop the circuit trace when the timer 0 is timeout.
*1 : The maximum address for the trace data storage space can be calculated by the following formula.
Maximum address for the trace data storage space = "Monitor buffer starting address" + "Monitor buffer size" - 1
