DVK90CAN1 Hardware User Guide
Interrupt 0 / 2
which is used in STK500.
Port A.0 drives the right LED (lsb) - index0 and Port A.7 drives the left LED (msb) -
index7.

Figure 3-28 . LEDs Implementation
The “INT” push-button receives its own filtering and is connected by default to the
asynchronous external interrupt INT[0]. If the “INT0/2” switch is set-up in the non-
default configuration, the “INT” push-button is connected to the asynchronous external
interrupt INT[2].
Pushing a push-button causes the corresponding signal to be pulled low, while releasing
(not pressed) gives a logical “1” without the need of pull-up resistor.
