5 ID System
The STK600 features an id system to identify which routing, socket and expansion
card is attached. The STK600 can impose voltage limitations based on the IDs, and
AVR Studio will notify the user if the combination is incorrect.
The ID system consists of two common output and two board unique input signals.
Each input is one of sixteen possible values based in the input signals – giving a total
id space of 256.
Three IDs are reserved for custom use and can be implemented without use of ICs.
Table 5-1. IDs reserved for custom use
Type ID
Board limited to 1.8 V 0xCA
Board limited to 3.3 V 0xCC
No limit on voltage 0xCF
The id 0xff indicates no board present.
