LIN Communications
The DEMO9S08EL32 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 enable LIN functionality. Two, 4-pin, Molex connectors
provide off-board connectivity. Figure 5 below shows the pin-out of the LIN connector looking
into the connector.

LIN_EN
The LIN_EN option header can be used to disable the LIN PHY under MCU control. The LIN
PHY is enabled by default if this header is removed. Figure 6 shows the LIN_EN shunt
positions.

COM_SEL
The COM_SEL option header connects the MCU SCI port to either the SCI PHY or the LIN
PHY. Figure 7 below shows jumper setting selecting between SCI or LIN signalling.
