CHAPTER 14 LIN-UART
14.6 Operations of LIN-UART and LIN-UART
Setting Procedure Example
14.6 Operations of LIN-UART and LIN-UART Setting
Procedure Example
The LIN-UART performs bi-directional serial communication in operating mode
0/2, master/slave communication in operating mode 1, LIN master/slave
communication in operating mode 3.
■ Operations of LIN-UART
● Operating mode
The LIN-UART has four operating modes (0 to 3), providing different connection methods
between CPUs and different data transfer methods as shown in Table 14.6-1.
The MD0 and MD1 bits in the LIN-UART serial mode register (SMR) are used to select the
following LIN-UART operating modes.
Notes:
• In operating mode 1, a system connecting to a master/slave supports both master
operations and slave operations.
• In operating mode 3, the communication format is fixed at "8-bit data, no parity bit, one
stop bit, LSB-first".
• If the operating mode is changed, all transmission operations and reception operations
are canceled, and the LIN-UART waits for the next transmission/reception.
