Preliminary document
Specifications in this document are tentative and subject to change.
Header Field Reception Flowchart Example (3)
TRJ register
completed flag
SFDCT bit in LINST register
SFDCT = 1?
YES
B
NO
The Synch Field for the hardware LIN
is measured.
A timer RJ interrupt can be used.
(The SBDCT bit is set when the timer
RJ counter underflows.)
If the SBE bit in the LINCT register is
set to 1 (unmasked after Synch Field
measurement completed), timer RJ
can be used in timer mode after the
SFDCT bit in the LINST register is set
to 1 and the RXDSF bit is set to 0.
Set the communication rate based
on the Synch Field measurement
result.
Communication is performed via
UART0.
(The SBDCT bit is set when the
timer RJ counter underflows.)
