23.11 External Programming
8210B–AVR–04/10
External Programming is the method for programming non volatile code and data into the device
from an external programmer or debugger. This can be done both in-system (In-System Pro-
gramming) or in mass production programming. The only restrictions on clock speed and voltage
is the maximum and minimum operating conditions for the device. Refer to the device datasheet
for details on this.
For external programming the device is accessed through the PDI and PDI Controller, using the
PDI physical connection. For details on PDI and how to enable and use the physical interface,
refer to
that the correct physical connection to the PDI is enabled.
Through the PDI, the external programmer access all NVM memories and NVM Controller using
the PDI Bus. Doing this all data and program memory spaces are mapped into the linear PDI
memory space.
for each memory space in the device.
