CLOCK CIRCUIT:
JUMPER DESCRIPTION:
INPUT/OUTPUT:
Quartz crystal 16 MHz is connected to AT90CAN128 pin 24 (XTAL1) and pin 23
(XTAL2).
Quartz crystal 32.768 kHz is connected to AT90CAN128 pin 19 (TOSC1/PG4) and
pin 18 (TOSC2/PG3) and supplies the internal Asynchronous Timer/Counter
(Timer/Counter2 in asynchronous operation).
CAN_D
CAN_T
AVREF_E
Status LED (red) with name STAT connected to AT90CAN128 pin 6
(OC3B/INT4/PE4).
Power-on LED (red) with name PWR_LED – this LED shows that +5V is applied to
the board.
User button with name BUT connected to AT90CAN128 pin 7 (OC3C/INT5/PE5).
Reset button with name RST connected to AT90CAN128 pin 20 (#RESET).
CAN Disable.
Default state is open.
This jumper assures correct work of the CAN. At each end of the bus
it should be closed. This means that if you have only two devices
with CAN, the jumpers of both devices should be closed. If you have
more than two devices, only the two end-devices should be closed.
Default state is closed.
This jumper when closed supplies VDDA reference to the AVREF. If
this jumper is open the desired reference voltage should be applied at
Default state is open.
EXT2-3.
If this jumper is closed, the CAN is disabled.
