17.6 LIN / UART Register Description

17.6.1 LIN Control Register - LINCR

• Bit 7 - LSWRES: Software Reset

– 0 = No action,

– 1 = Software reset (this bit is self-reset at the end of the reset procedure).

• Bit 6 - LIN13: LIN 1.3 mode

– 0 = LIN 2.1 (default),

– 1 = LIN 1.3.

• Bit 5:4 - LCONF[1:0]: Configuration

a. LIN mode (default = 00):

–00 = LIN Standard configuration (listen mode “off”, CRC “on” & Frame_Time_Out “on”,

– 01 = No CRC, no Time out (listen mode “off”),
