Types Of Breakpoints And How To Set; Trace Windows - Fujitsu MB95100 Series Application Note

4.3.3 Types of breakpoints and how to set

There are three types of breakpoint as follows:
Select [Breakpoint] from the [Debug] menu to open the [Break] dialog.
This dialog can also set breakpoints. It also provides a list of set breakpoints.
• Code breakpoint
Code breakpoint is a breakpoint to stop the program when the PC attempts to
execute a set address. For both Simulator and Emulator, the PC stop position
is a breakpoint before execution. Up to 256 code breakpoints can be set.
• Data breakpoint
Data breakpoint is a breakpoint to stop program when the PC accesses data
at a set address. Read, write, and read/write can be set as access conditions.
Up to two data breakpoints can be set.
• Sequence breakpoint
This breakpoint stops the program being executed when the program is
executed at two specified addresses from "Level 1" to "Level 2."

4.3.4 Trace Windows

When the trace function is enabled, data is always sampled and stored in the trace
buffer during execution.
Trace information to be actually displayed is that on the 16 branches immediately
preceding suspension of execution.
The trace buffer is structually a ring-shaped, so data is overwritten automatically
from the beginning of the sequence buffer when the trace buffer is full.
1. Select [Trace] from the [View] menu to open the trace window.
