31.2 Overview
The Program and Debug Interface (PDI) is an Atmel proprietary interface for external programming and on-chip
debugging of a device. The PDI supports fast programming of nonvolatile memory (NVM) spaces; flash, EEPOM, fuses,
lock bits, and the user signature row.
Debug is supported through an on-chip debug system that offers nonintrusive, real-time debug. It does not require any
software or hardware resources except for the device pin connection. Using the Atmel tool chain, it offers complete
program flow control and support for an unlimited number of program and complex data breakpoints. Application debug
can be done from a C or other high-level language source code level, as well as from an assembler and disassemble
level.
Programming and debugging can be done through the PDI physical layer. This is a two-pin interface that uses the Reset
pin for the clock input (PDI_CLK) and one other dedicated pin for data input and output (PDI_DATA). Any external
programmer or on-chip debugger/emulator can be directly connected to this interface.
