Description
Branch instruction trace functions which are built into the
device. This function displays the branch source and branch
destination addresses and instruction words, and enables a
realtime trace.
This function is operational when the AUD pins are connected
to the emulator. This function displays the branch source and
branch destination addresses, and instruction words at the
branch destination.
When the next branch occurs while the trace information is
output, the output of the information is stopped and the next
trace information is output. The user program can be executed
in realtime, but some trace information may be lost.
This function is operational when the AUD pins are connected
to the emulator. This function displays the branch source and
branch destination addresses, and instruction words at the
branch destination.
When the next branch occurs while the trace information is
being output, the CPU stops operations until the information is
output. The user program may not be executed in realtime.
Trace continue function:
When the trace buffer becomes full, this function overwrites
the oldest trace information to store the latest trace
information.
Trace stop function:
After the trace buffer becomes full, the trace information is
no longer acquired. (The user program is continuously
executed.)
