Debug sessions on UC3 target devices over the aWire interface will be automatically tuned to the optimal
baud rate by the Atmel-ICE itself. However, if you are experiencing reliability problems related to a noisy
debug environment, it is possible to force the aWire speed below a configurable limit.
Debug sessions on SAM target devices over the SWD interface can be clocked at up to ten times the CPU
clock (but limited to 2MHz max).
● Preserve EEPROM
Select this option to avoid erasing the EEPROM during reprogramming of the target before a debug
session.
● Use external reset
If your target application disables the JTAG interface, the external reset must be pulled low during
programming. Selecting this option avoids repeatedly being asked whether to use the external reset.
