Header Field Reception Flowchart Example (3)
Read the Synch Field measurement-
completed flag
SFDCT flag in LINST register
SFDCT = 1?
YES
B
NO
A Synch Field for the hardware LIN
is measured.
A timer RA interrupt can be used.
(The SBDCT flag is set when
the timer RA counter underflows.)
If the SBE bit in the LINCR register
is set to 1 (unmasked after Synch
Field measurement completed),
timer RA can be used in timer mode
after the SFDCT flag in the LINST
register is set to 1 and the RXDSF
flag is set to 0.
Set a communication rate based on
the Synch Field measurement
result.
Communication is performed via
UART0.
(The SBDCT flag is set when
the timer RA counter underflows.)
