Trace Functions
Realtime trace
Non realtime trace
Branch instruction trace functions which are built into the
Description
chip. This function displays the branch source and branch
destination addresses and enables a realtime trace.
This function is operational when the AUD pin is 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 information is stopped and the next trace
information is output. The user program can be executed in
realtime, but some trace information will not be output.
When the trace buffer becomes full, this function always
overwrites the oldest trace information to acquire the latest
trace information.
After the trace buffer becomes full, the trace information is
not acquired. (The user program is continuously executed.)
This function is operational when the AUD pin is connected

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 is not executed in realtime.
