12.7 LIN Communication Operation
12.7.1 LIN transmission
Of UART transmission, UART2 of the 32, 48, and 64-pin products support LIN communication.
For LIN transmission, channel 0 of unit 1 is used.

Note Use this operation within a range that satisfies the conditions above and the peripheral functions characteristics in
the electrical specifications (see CHAPTER 29 ELECTRICAL SPECIFICATIONS (T
A = −40 to +85°C),
CHAPTER 30 ELECTRICAL SPECIFICATIONS (G: INDUSTRIAL APPLICATIONS TA = −40 to +105°C)). In
addition, LIN communication is usually 2.4/9.6/19.2 kbps is often used.
