29.1 Overview
29.2 Method of Connecting to On-Chip Debug Emulator
This LSI has an on-chip debug function allowing Flash memory rewriting.
The on-chip debug emulator (uEASE) is connected to this LSI to perform the on-chip debug function.
Figure 29-1 shows connection to the on-chip debug emulator (uEASE).
For on-chip debug emulator, see “uEASE User’s Manual”.
Note:
− Please do not apply LSIs used for debugging to mass production.
− When using the on-chip debug function or the flash rewrite function after mounting of the board, design the board
so that the 6 pins (V
can be connected.
− “3.0V to 3.6V” has to be supplied to VDD while debugging and writing flash.
− When the system reset circuit is included in the user application circuit, enable switching of the connection in the
user application circuit, as shown above. When the system reset circuit is not included in the user application circuit,
the RESET_N pin can be connected directy to the RESET_N pin of this LSI.
For details, see “uEASE User’s Manual” and “uEASE Target Connection Manual”.
