The “VCC-ON“ LED is always lit when power is applied to DVK90CAN1 regardless of
power supply source and the regulation.

(c.f.
Although the AT90CAN128 has its on-chip RESET circuitry (c.f. AT90CAN128
Datasheet, section “System Control and Reset), the DVK90CAN1 provides to the
AT90CAN128 a RESET signal witch can come from 3 different sources:
The on-board RC network acts as power-on RESET.
By pressing the RESET push button on the DVK90CAN1, a warm RESET of the
AT90CAN128 is performed.
