The XMEGA D4 has a powerful On-Chip Debug (OCD) system that - in combination with Atmel’s
development tools - provides all the necessary functions to debug an application. It has support
for program and data breakpoints, and can debug an application from C and high level language
source code level, as well as assembler and disassembler level. It has full Non-Intrusive Opera-
tion and no hardware or software resources in the device are used. The ODC system is
accessed through an external debugging tool which connects to the PDI physical interface.
