On-Chip Debugger
Overview
The Z8F640x family devices have an integrated On-Chip Debugger (OCD) that provides
advanced debugging features including:
• Reading and writing of the Register File
• Reading and writing of Program and Data Memory
• Setting of Breakpoints and Watchpoints
• Execution of eZ8 CPU instructions.
Architecture
The On-Chip Debugger consists of four primary functional blocks: transmitter, receiver,
auto-baud generator, and debug controller. Figure 86 illustrates the architecture of the On-
