NOTE:
If the target board powers the LIN bus in Master mode, +12V must be
applied externally at connector J11.
MSTR Option
The MSTR option jumper allows the LIN transceiver to be configured for master mode
functionality. Master mode may also be set using the INH pin. Refer to the MC33661 device
datasheet for details on use and configuration. Refer to Figure 11 below.

NOTE: LIN PHY may also be configured as a Master Node using the INH pin. Refer to the LIN
PHY data sheet for details.
LIN Connector
The DEMO9S12XHY256 supports two, 2 x 2 Molex connectors to interface to the LIN bus.
One connector (J9) is not installed in default configurations.
