AUX port
Figure 9-4.
The Auxiliary (AUX) port and messaging protocol follow the definitions of the Nexus standard.
This standard allows varying the number of signalling pins. The following configuration is
selected for AVR32UC.
The configuration is based on the presumed needs for bandwidth in a system being traced at
100+ MIPS, balanced against the desire to keep debug pincount low. This configuration can be
changed in future implementations to allow for greater or smaller bandwidth over the AUX port.
The AUX pins may be multiplexed with GPIO in a device. By default, the MCKO, MDO, and
MSEO pins are tristated or used as GPIO, and the Nexus functionality must be explicitly enabled
by the debugger. EVTO, EVTI, and the JTAG pins are always available to the debugger.
If the AUX pins are needed for Nexus functionality in an application, it is recommended not to
use these pins for GPIO purposes, as this can affect the signal integrity required for Nexus
operation.
• 6 data output pins (MDO)
• 2 message start/end output pins (MSEO)
• 1 EVTO pin
• 1 EVTI pin
