LIN-J1 / J2 PORTS
The LIN ports provide parallel connectors for attaching a LIN network. Providing two
connectors enables the user to either connect additional slave nodes or monitoring / test tools
to the board without special wiring harness creation. The QL4 device provides a LIN Slave
type node on the LIN Network. A LIN physical layer transceiver (MC33661, or similar) is
provided between the QL4 device and the LIN network connectors. Refer to the MC33661
data sheet for complete details of transceiver operation. The following diagram represents the
LIN connection:

The LIN interface provides optional features of Enable control (LIN_EN option), Wake switch,
and input power source option - PWR_SEL. See the PWR_SEL option in the power supply
section of this manual for information on this option.
LIN_EN Option
The LIN_EN option allows enable control of the LIN transceiver. With a transceiver such as the
MC33661, software control of the EN pin allows the user to set the slew rate control of the
transceiver. This feature allows the EMC characteristics of the physical layer to be tuned to
the needs of the application. Three options are available:
LIN_EN = OPEN: (No option jumper installed) The transceiver is disabled and in sleep mode,
no LIN output messages will be possible. Pin 2 of the option pins can be wired to any available
HC08 port to provide the enable signal. The WAKE switch maybe applied to enable the
transceiver also.
LIN_EN = 1-2 jumper position: QL4 port PBT7 provides transceiver output control. PTB7
output high will enable the transceiver to allow LIN messages.
LIN_EN = 2-3 jumper position: Transceiver is always enabled. Port PTB7 maybe applied for
other purposes with this option setting.
WAKE Switch
The WAKE switch applies the Wake up function of the transceiver. With LIN_EN option open,
the switch will wake-up the transceiver. Wake also has a test pad for remote connections.
