TriBoard Information
Per default the miniWiggler is connected to the DAP. If resistors R214, R215 and R216 assembled (default) then
the standard DAP is connected to miniWiggler. If all this resistors are not assembled then the miniWiggler can’t
be used. In this case only the DAP connectors X402 and X406 can be used. See
.

FlexRay™ (E-RAY)
The board has 2 IDC10 plugs for FlexRay™ Communication (channel A and B) with up to 10 Mbit/s. For the pinout
of the plugs see
. You can use a IDC female connector with crimpconnector, flat cable and SUB-D 9 plug
with crimpconnector to have a 1:1 adapter to SUB-D 9.
The transceiver are connected to the TriCore device via zero ohm resistors (R320 up to R324 and R340 up to R344)
which must be removed to use the ports outside.
ERAY-A can be connected to P02.0, P02.1 and P02.4. Transceiver for channel A can be enabled/disabled via P20.8.
The error state of transceiver channel A can be read out via P20.9.
ERAY-B is connected to P02.2, P02.3 and P02.5. Transceiver for channel B can be enabled/disabled via P02.6. The
error state of transceiver channel A can be read out via P02.7.
For more information look in the user manual for TC3X4 TQFP.
3.8
Serial Eeprom
The QSPI1 of the TC3X4 TQFP is connected to a serial EEPROM with a size of 2KBit (256 x 8). As chip select for this
EEPROM is used the port pin P23.1. P23.1 has no chip select functionality of QSPI. Therefore the software must
generate the chip select manual via bit banging. To disconnect (disable) the EEPROM remove resistor R348.
3.9
MultiCAN
On the board are two CAN transceiver connected to the CAN0 and CAN1 of TC3X4 TQFP. The transceivers are
connected to two IDC10 plug. For the pinout of IDC10 plug see
. You can use a IDC female connector with
crimpconnector, flat cable and SUB-D 9 plug with crimpconnector to have a 1:1 adapter to SUB-D 9.
The transceiver are connected to the TriCore device via zero ohm resistors (R301 up to R304 and R311 up to R314)
which must be removed to use the ports outside.
CAN0 can be used via P11.10 and P11.12 (CAN0 node 3, default) or P14.0 and P14.1 (CAN0 node 1). CAN1 can be
used via P15.2 and P15.3 (CAN0 node 1, default) or P00.0 and P00.1 (CAN1 node 0).
3.10
LIN
On the board is one LIN transceiver connected to the ASCLIN1 on TC3X4 TQFP (P15.0 and P15.1). The transceiver
are connected to one IDC10 plug. For the pinout of IDC10 plug see
. You can use a IDC female connector
with crimpconnector, flat cable and SUB-D 9 plug with crimpconnector to have a 1:1 adapter to SUB-D 9.
To disconnect the LIN remove resistor R364 and R365.
The LIN can be used in master and in slave mode. For the master mode there is per default a pull-up of 1K (R360)
and a capacitor of 1nF (C304) on the BUS assembled. For using the LIN in slave mode the pull-up resistor R360
must be removed and maybe the capacitor changed to a smaller value (e.g. 220pF).
The mentioned resistor and capacitor are red marked in
