Message protocol
To be able to use AUX-based debug tools for AVR32, a circuit design using an AVR32 device
should use a Mictor38 connector (AMP P/N 767054-1) as defined in the Nexus standard, with
the pinout shown in Table 9-19.
Table 9-19.
The Nexus standard specifies that the AUX port can be enabled by keeping EVTI low while puls-
ing TRST (or exiting Test-Logic-Reset). The OCD system in AVR32 has removed this feature. In
order to enable the AUX port, the debugger has to write the AXC:AXE (Auxiliary Enable) bit.
The OCD System implements the Auxiliary Port Message Protocol defined in the Nexus stan-
dard. The following section is merely a summary of this protocol. For details, please see the
Nexus standard.
Messages are composed of a Start-of-Message (SOM) token, followed by one or more packets
of information, each of fixed or variable length, and ended by an End-of-Message (EOM) token.
SOM/EOM and End-of-Variable-Length-Packets (EVLP) are signalled by MSEO for transmitted
messages. Packet information is carried by the MDO pins. The number of MDO pins available is
known as the port boundary. The information carried by the MDO and MSEO pins each cycle is
known as a frame.
