3.4 Debugger/Programmer

By default, the on-board debugger (PKOB4) is connected to the programming pins (SWDIO and SWDCLK) of the WBZ450PE Module.

The voltage level translators are provided on signals between PKOB4 and WBZ450PE Module for supporting target voltage from 1.9-3.6V.

Two PKOB4 LEDs indicate:
  • Green (D1) – ACTIVE indicator
  • Yellow (D2) – STATUS indicator

In addition, the WBZ450 Curiosity Board supports external debuggers, such as MPLAB ICD4, MPLAB PICKIT4 and MPLAB SNAP by connecting to the debug connector (J10).

The debug connector (J10) follows the standard ARM SWD 10. MPLAB ICD4 can be connected to the DBG header using the debugger adapter board (AC102015). For more details, refer to the Debugger Adapter Board (AC102015).
