Features
Overview
•
•
•
The Program and Debug Interface (PDI) is an Atmel proprietary interface for external program-
ming and on-chip debugging of the device.
The PDI supports high-speed programming of all Non-Volatile Memory (NVM) spaces; Flash,
EEPOM, Fuses, Lockbits and the User Signature Row. This is done by accessing the NVM Con-
troller, and executing NVM Controller commands as described in Memory Programming.
The On-Chip Debug (OCD) system supports fully intrusive operation. During debugging no soft-
ware or hardware resources in the device is used. The OCD system has full program flow
control, supports unlimited number of program and data breakpoints and has full access
(read/write) to all memories.
Both programming and debugging can be done through two physical interfaces. The primary
interface is the PDI Physical. This is a 2-pin interface using the Reset pin for the clock input
(PDI_CLK), and the dedicated Test pin for data input and output (PDI_DATA). Unless otherwise
stated, all references to the PDI assumes access through the PDI physical. Any external pro-
grammer or on-chip debugger/emulator can be directly connected to these interfaces, and no
external components are required.
