Figure 22.10
22.4.4
Timer RJ Set the timer to stop counting
Timer RJ Read the count status flag
UART0 Transmission completes via UART
Hardware LIN Clear the status flags
Hardware LIN Set the LIN operation to stop
Figure 22.10 shows an Example of Hardware LIN Communication Completion Flowchart.
Use the following timing for hardware LIN ending processing:
• If the hardware bus collision detection function is used
• If the bus collision detection function is not used
Perform hardware LIN ending processing after checksum transmission completes.
Perform hardware LIN end processing after header field transmission and reception complete.
(Bus collision detection, Synch Break detection, Synch
Field measurement)
Bits B2CLR, B1CLR, B0CLR in LINST register  1
Hardware LIN End Processing
Preliminary document
Specifications in this document are tentative and subject to change.
TSTART bit in TRJCR register  0
TCSTF flag in TRJCR register
Example of Hardware LIN Communication Completion Flowchart
LINE bit in LINCT register  0
TCSTF = 0 ?
YES
NO
Set the timer to stop counting.
Zero or one cycle of the timer RJ
count source is required after
timer RJ stops counting before
the TCSTF bit is set to 1.
If the bus collision detection
function is not used, UART0
transmission completion
processing is not required.
After clearing the hardware LIN
status flag, stop the hardware
LIN operation.
