Timer RA
Timer RA
UART0 Complete transmission via UART0
Hardware LIN Clear the status flags
Hardware LIN Set the LIN operation to stop
Figure 17.12 shows an Example of Hardware LIN Communication Completion Flowchart.
Use the following timing for hardware LIN end processing:
•
•
If the hardware bus collision detection function is used
Perform hardware LIN end processing after checksum transmission completes.
If the bus collision detection function is not used
Perform hardware LIN end processing after header field transmission and reception complete.
Hardware LIN End Processing
Set the timer to stop counting
TSTART bit in TRACR register ← 0
Read the count status flag
TCSTF flag in TRACR register
Example of Hardware LIN Communication Completion Flowchart
(Bus collision detection, Synch Break detection, Synch
Field measurement)
Bits B2CLR, B1CLR, B0CLR in the LINST register ← 1
LINE bit in the LINCR register ← 0

TCSTF = 0 ?
YES
NO
Set the timer to stop counting.
Zero to one cycle of the timer RA
count source is required after timer
RA starts counting before the
TCSTF flag is set to 1.
When the bus collision detection
function is not used, end
processing for the UART0
transmission is not required.
After clearing hardware LIN
status flag, stop the
hardware LIN operation.
