The XMEGA A3B 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-Intru-
sive Operation 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 JTAG or PDI physical
interfaces. Refer to
Complete Program Flow Control
Debugging on C and high-level language source code level
Debugging on Assembler and disassembler level
1 dedicated program address or source level breakpoint for AVR Studio / debugger
4 Hardware Breakpoints
Unlimited Number of User Program Breakpoints
Unlimited Number of User Data Breakpoints, with break on:
