HCS08 On-Chip DBG
Module
The HCS08 derivatives featuring an on-chip DBG module require a debugger graphical
user interface to setup this module and take full advantage of this enhanced debugging
feature. This chapter describes the debugger DBG module user interface.
Within several HCS08 debugger connections (e.g. P&E Debug), the HCS08 Serial
Monitor and inDART-HCS08, a complete graphical user interface is provided. A trigger
setup dialog box and context sensitive context menus (right-click) in the Source,
Assembly, Data and Memory component windows are used to set the on-chip DBG
module and triggers.
This DBG module support is automatically enabled or disabled, according to derivative
selected by user or automatically through the device Part Id.
Reference Document
The HCS08 on-chip DBG module described in this chapter is also described in the
HCS08RMv1/D, Rev. 1, 6/2003 Freescale document.
DBG Features
The debugger covers all features available within the on-chip DBG module:
• Regular hardware breakpoints and watchpoints
• Predefined preset Instruction Triggers , Memory Access Triggers or Capture
Triggers , a wide set of complex hardware breakpoints (triggers on program code
instructions) and watchpoints (triggers on device memory access) and data bus
recording
• Expert Triggers, as powerful as predefined preset triggers
• Code program flow rebuild from DBG data capture within the Trace window
component (open the Trace component to display the code program flow rebuild).
