23.6 Usage Notes
1. An UDI command, once set, will not be modified as long as another command is not re-issued
from the UDI. If the same command is given continuously, the command must be set after a
command (BYPASS, etc.) that does not affect chip operations is once set.
2. Because chip operations are suspended in standby mode, UDI commands are not accepted. To
keep the TAP state constant before and after standby mode, TCK must be high during standby
mode transition.
3. The UDI is used for emulator connection. Therefore, UDI functions cannot be used when using
an emulator.
23.7 Advanced User Debugger (AUD)
The AUD is a function only for an emulator. For details on the AUD, refer to each emulator’s
User’s Manual.
