Figure 2-1.Connecting the STK594 to the STK500 Board

Note: Connecting the STK594 with the wrong orientation may damage the boards.

Note: Do not mount the STK594 at the same time an AVR is mounted on the STK500 board.

2.2PORT Connectors

2.2.1PORT E

Since the AT94K devices have additional ports not available on the STK500, these ports are located on the STK594 board. The STK594 ports have the same pinout and func- tionality as the ports on the STK500 board. Since Port A to Port D are already present on the STK500 board, they are not duplicated on the STK594.

Figure 2-2 shows the pinout for the I/O port headers Port E.

PORT E

Note: Port E is also present on the STK500, but only PE0 to PE2 (3 least significant bits) are accessible. To access all Port E bits the connector on the STK594 must be used.
