CHAPTER 14 LIN-UART
14.6 Operations of LIN-UART and LIN-UART
Setting Procedure Example
• LIN-UART serial status register (SSR)
BDS : "0"– LSB-first, "1"– MSB-first
RIE : "1"– Enables receive interrupts, "0"– Disables receive interrupts
TIE : "1"– Enables transmit interrupts, "0"– Disables transmit interrupts
• LIN-UART extended communication control register (ECCR)
SSM: "0"– Not use start/stop bits (normal),
"1"– Uses start/stop bits (extended function),
MS : "0"– Serial clock transmission side (serial clock output),
"1"– Serial clock reception side (inputs serial clock from the device on the serial
clock transmission side)
Note:
To start communication, write data to the LIN-UART transmit data register (TDR).
To receive data only, disable the serial output (SMR:SOE = 0), and then write dummy
data to the TDR register.
Enabling continuous clock output and the start/stop bits enables bi-directional
communication as that in asynchronous mode.
