•USB was not selected on the HEW Init dialog box.

Please select ‘USB’ from the Init dialog box that is displayed right after you start a debug session.

•The selected MCU on the ICD board and the actual target MCU (M16C/28) do not match.

Close the error message by clicking on the ‘OK’ button, then click on the ‘Cancel’ button of the Init window. Make sure you select ‘M30280FA.mcu’. If the MCU loaded on the ICD is different, HEW will re-program the ICD to match it.

•The target MCU is damaged.

Try a different target board and see if the HEW will connect. You may have a damaged board or MCU.

A.3.3 Issues that May Arise During Debug Operations

While debugging user code, some issues may come up because the limitations discussed in section “7.0 System Operation & Limitations” were not satisfied. The common issues are listed in Table A.3, including the countermeasures.

To re-initialize the system without closing a debug session, try the following:

•Click the [OK] button on the error dialog box to close it.

•When an Exit dialog box appears, click the [Cancel] button to close it.
