Section 2 Software Specifications when Using the SH72546RFCC, SH72544R, SH72543R, SH72531FCC,
and SH72531
• Writing memory immediately before generating a break
If an instruction is executed to write memory immediately before generating a break, trace
acquisition may not be performed.
• Internal trace function is not available for the SH72544R, SH72543R, and SH72531.
(3) AUD Trace Functions
This function is operational when the AUD pin of the device is connected to the emulator. Table
2.14 shows the AUD trace acquisition mode that can be set in each trace function.

Description
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.
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.
This function overwrites the latest trace information to store
the oldest trace information.
After the trace buffer becomes full, the trace information is no
longer acquired. The user program is continuously executed.
