Table 2.7 Trace Functions

Function Description

Internal trace Branch instruction trace functions which are built into the

chip. This function displays the branch source and branch

destination addresses and enables a realtime trace.

AUD trace* 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.

• Trace continue mode:

When the trace buffer becomes full, this function always

overwrites the oldest trace information to acquire the latest

trace information.

• Trace stop mode:

After the trace buffer becomes full, the trace information is

not acquired. (The user program is continuously executed.)

Non realtime trace This function is operational when the AUD pin is connected
