RS-232
An RS-232 translator provides RS-232 to TTL/CMOS logic level translation on the COM
connector. The COM connector is a 9-pin Dsub, right-angle connector. A ferrite bead on
shield ground provides conducted immunity protection. Communication signals TXD1 and
RXD1 are routed from the transceiver to the MCU. Hardware flow control signals RTS and
CTS are available on the logic side of the transceiver. These signals are routed to vias located
near the transceiver.
communications.

COM Connector
A standard 9-pin Dsub connector provides external connections for the SCI0 port. The Dsub
shell is connected to board ground through a ferrite bead. The ferrite bead provides noise
isolation on the RS-232 connection. The figure below details the DB9 connector.

LIN Communications
The DEMO9S08SH32/SG32 applies a fault tolerant, Local Interconnect Interface (LIN)
physical layer (PHY) for use in developing automotive control applications. The PHY supports
LIN bus functionality for input voltages between +12V and +18V. Only power applied to the
PWR connector or through the LIN bus will enable LIN functionality.
connectors provide off-board connectivity. The figure below shows the pin-out of the LIN
connector looking into the connector.
