Hardware LIN Clear the status flags
Hardware LIN Set the LIN operation to stop
Figure 27.10 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
Transmission completes via UART0
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 LINST register ← 1
LINE bit in LINCR register ← 0
TCSTF = 0?
YES
NO
Set the timer to stop counting.
Zero or one cycle of the timer RA
count source is required after
timer RA stops counting before
the TCSTF flag 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.
