LIN / UART Description

Reset
Clock
LIN Protocol Selection
The AVR core reset logic signal also resets the LIN/UART controller. Another form of reset
exists, a software reset controlled by LSWRES bit in LINCR register. This self-reset bit per-
forms a partial reset as shown in
Table 17-2.
The I/O clock signal (clk
LIN13 bit in LINCR register is used to select the LIN protocol:
The controller checks the LIN13 bit in computing the checksum (enhanced checksum in
LIN2.1 / classic checksum in LIN 1.3). See
This bit is irrelevant for UART commands.
• LIN13 = 0 (default): LIN 2.1 protocol,
• LIN13 = 1: LIN 1.3 protocol.
