9.
10. The “SERIAL SETTINGS” section has two jumpers (“TXD SEL” and
11. The “CAN” section contains one fault-tolerant (up to 125 Kbaud)
12. A prototype area features both a standard, thru-hole area (for
4
Use the “RXD SEL” and “TXD SEL” jumpers in the “SERIAL
SETTINGS” section of the board to select whether to use the RS-
232, LIN, or to free the microcontroller’s PTE0/TXD and PTE1/RXD
lines. A 9-pin, D-Sub female connector is provided for the RS-232
channel.
The “LIN” section contains one LIN transceiver, capable of a speed
of up to 100 Kbps in fast mode. The LIN node can be configured as
a master node via the “MASTER NODE ENA” jumper, which inserts
a 3.3 KOhm resistor between the LIN bus line and the LIN
transceiver power supply line. The LIN transceiver can be powered
either by the Starter Kit’s internal 12 V DC reference, or by the LIN
network itself, via the “TRANSCEIVER SUPPLY SEL” jumper.
Analogously, the LIN network can be supplied by the Starter Kit’s
internal 12 V DC reference via the “LIN SUPPLY ENA” jumper. The
microcontroller’s PTE0/TXD and PTE1/RXD lines used by the LIN
transceiver are shared with the RS-232 transceiver’s TXD and RXD
line. Use the “TXD SEL” and “RXD SEL” jumpers in the “SERIAL
SETTINGS” section of the board to select whether to use the RS-
232, LIN, or to free the microcontroller’s PTE0/TXD and PTE1/RXD
lines. A 3x1 male header connector is provided to interface to an
external LIN bus.
“RXD SEL”) that allow the use of the SCI peripheral of the
microcontroller to be chosen. The SCI peripheral can be connected
to the LIN node or to the RS-232 channel , or can be freed by
removing all jumpers.
CAN transceiver. The TX and RX signals of CAN node can be
disconnected by removing the “CANTX ENA” and “CANRX ENA”
jumpers from the microcontroller’s CANTX and CANRX pins. A 3x1
male header connector is provided to interface to an external CAN
bus.

SMD components). Additionally, all of the board’s supply lines (12 V,
VDD and GND lines) are provided.
