LIN Enable Bit<br />

0 The LIN Physical Layer is in shutdown mode. None of the functionalities is available, except that the bus line<br />

is held in its recessive state by a high ohmic (330kΩ) resistor.<br />

1 The LIN Physical Layer is not in shutdown mode.<br />

Receive Only Mode bit<br />

This bit can be normally written in normal mode.<br />

If an over-current condition occurs it will be set to 1 and it is write protected until the over-current condition is<br />

gone. See mode description for details.<br />

0 The LIN Physical Layer is not in receive only mode.<br />

1 The LIN Physical Layer is in receive only mode.<br />

LIN Wake-Up Enable<br />

0 The wake-up feature is disabled when being in standby mode.<br />

1 The wake-up feature is enabled when being in standby mode.<br />

LIN Pull-Up Enable<br />

0 The pull-up resistor is high ohmic (330kΩ).<br />

1 If LPE=1, the pull-up resistor is the one specified in the LIN specification (30kΩ).<br />
