3.7.1 Event Breakpoint
For the CE2000-H8S/2238 emulator, two event breakpoints are supplied permanently. The conditions to
determine the breaks are
•
Address
•
Access (Read/Write)
The break condition occurs in a “AND” condition. If the factors defined are not fulfilled, the particular
break condition will be ignored. Each factor can be masked or ignored.
Since the event breakpoint is still under development, user can use the PFG Breakpoints instead.

Two PFG breakpoints can be downloaded into the PFG. The PFG Event Breaks have the following
conditions:
•
Address
•
Data
•
Access (Read/Write)

of the timer is 50ns. There is no time limit for this counter.
The runtime can be observed in the Status window during the run mode.
3.9 PFG Function - Trace
There is no permanent trace provided. However, user can download the Trace Function into the PFG to
keep track of the program. The Trace provided is a 256-cycle trace. The Trace function will display the
