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 (except for four I/O pins required if JTAG
connection 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
