AUD Trace Functions: This function is operational when the AUD pin of the device is
connected to the emulator. It is activated by selecting the [AUD trace] radio button in the [Trace
type] group box of the [Trace mode] page. Set the trace condition to be used.
Table 2.8 shows the AUD trace acquisition mode that can be set in each trace function.
Table 2.8 AUD Trace Acquisition Mode
Type Mode Description
Continuous
trace occurs
Realtime trace When the next branch occurs while the trace information is
being output, all the information may not be output. The user
program can be executed in realtime, but some trace
information will be lost.
Non realtime trace 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.
Trace buffer
full
Trace continue This function overwrites the oldest trace information to store
the latest trace information.
Trace stop After the trace buffer becomes full, the trace information is no
longer acquired. The user program is continuously executed.
AUD pin 4 bits The trace data is acquired from the 4-bit AUDATA pin.
8 bits The trace data is acquired from the 8-bit AUDATA pin. This
mode is not available when the SH7752 is used.
Note: When the AUD trace is enabled, the emulator forcibly changes the pin functions of the
specified port as the AUD functions.
