Operation Of Lin-Uart - Fujitsu F2MCTM-16LX Hardware Manual

CHAPTER 20 LIN-UART

Operation of LIN-UART

LIN-UART operates in operation mode 0 for normal bidirectional serial communication,
in mode 2 and 3 in bidirectional communication as master or slave, and in mode 1 as
master or slave in multiprocessor communication.
Operation of LIN-UART
Operation modes
There are four LIN-UART operation modes: modes 0 to 3. As listed in Table 20.7-1 , an operation mode
can be selected according to the communication method.
Table 20.7-1 Operation Mode of LIN-UART
Operation mode
0 Normal mode
1 Multiprocessor

2 Normal mode
3 LIN mode
-: Setting disabled
*: "+1" means the indicator bit of the address/data selection used for controlling communication in the multiprocessor mode.
Note:
Mode 1 operation is supported both for master or slave operation of LIN-UART in a master-slave
connection system. In Mode 3, the LIN-UART function is locked to 8N1-Format, LSB first.
If the mode is changed, LIN-UART cuts off all possible transmission or reception and awaits then new
action.
