closed*
Pin 5 on CAN transceivers U605 and U606 not
connected to 3.3 V supply voltage VDD_V3V3
(use only with 82C251 devices)
open

Table 22: J616 CAN Transceiver Supply Configuration
3.14 J602, J603, J604, J605 CAN Interfaces
Two CAN interfaces are provided by the phyCORE-LPC2292/94. The
CAN signals extend to the two TLE6250V33 CAN transceivers at
U605 and U606. The CAN transceivers generate the corresponding
CAN_H1, CAN_L1, CAN_H2 and CAN_L2 signals. These signals
can be directly connected to a CAN dual-wire bus.
In order to use external (opto-isolated) transceivers, direct access to
the CAN1Rx, CAN1Tx, CAN2Rx and CAN2Tx signals is also
available at the phyCORE-connector X700. This requires
both
removal of the on-board CAN transceiver devices and closing
Jumpers J602, J603, J604 and J605.
