On-Chip Debugger
Z8 Encore! XP F0823 Series devices contain an integrated On-Chip Debugger (OCD)
which provides advanced debugging features that include:
• Single pin interface
• Reading and writing of the register file
• Reading and writing of program and data memory
• Setting of breakpoints and watchpoints
• Executing eZ8 CPU instructions
• Debug pin sharing with general-purpose input-output function to maximize the pins
available
Architecture
The on-chip debugger consists of four primary functional blocks: transmitter, receiver,
auto-baud detector/generator, and debug controller. Figure 22 displays the architecture of
the OCD.
