Notes on AUD Trace:
1. When the trace display is performed during user program execution, the mnemonics, operands,
or source is not displayed.
2. The AUD branch trace function outputs the differences between newly output branch source
addresses and previously output branch source addresses. The window trace function outputs
the differences between newly output addresses and previously output addresses. If the
previously output address is the same as the upper 16 bits, the lower 16 bits are output. If it
matches the upper 24 bits, the lower 8 bits are output. If it matches the upper 28 bits, the lower
4 bits are output.
The emulator regenerates the 32-bit address from these differences and displays it in the
[Trace] window. If the emulator cannot display the 32-bit address, it displays the difference
from the previously displayed 32-bit address.
3. If the 32-bit address cannot be displayed, the source line is not displayed.
4. In the emulator, when multiple loops are performed to reduce the number of AUD trace
displays, only the IP counts up.
5. In the emulator, the maximum number of trace displays is 65534 lines (32767 branches).
However, the maximum number of trace displays differs according to the AUD trace
information to be output. Therefore, the above pointers cannot be always acquired.
6. The AUD trace acquisition is not available when [User] is selected in the [UBC mode] list box
of the [Configuration] dialog box. In this case, close the [Trace] window.
7. Do not use the AUD full-trace mode for the VIO function.
8. If a completion-type exception occurs during exception branch acquisition, the next address to
the address in which an exception occurs is acquired.
