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
• If the bus collision detection function is not used
Sep 26, 2008
Perform hardware LIN end processing after checksum transmission completes.
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
Clear the status flags
(Bus collision detection, Synch Break
detection, Synch Field measurement)
Bits B2CLR, B1CLR, B0CLR in the LINST
register ← 0
Set the LIN operation to stop
LINE bit in the LINCR register ← 0
Page 335 of 453
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.
