bit 7-3

Unimplemented: Read as '0'

bit 2

LINTX: LIN Bus Transmit bit

1 = LIN Bus line is high

0 = LIN Bus line is low

bit 1

Unimplemented: Read as '0'

bit 0

LINVDD: LIN Bus Transceiver VDD Supply bit

1 = VDD is supplied to the LIN Bus transceiver via microcontroller

0 = VDD is not supplied to the LIN Bus transceiver

Note 1: Transceiver VDD is same as microcontroller VDD.

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
