Rx Header / LIN Abort Function
Table 15-1.
Setting the LENA bit in LINCR register enables the LIN/UART controller. To disable the
LIN/UART controller, LENA bit must be written to 0. No wait states are implemented, so, the
disable command is taken into account immediately.
Clearing the LCMD[2] bit in LINCR register enables LIN commands.
As shown in
LINCR register are available (c.f.
This function (or state) is mainly the withdrawal mode of the controller.
When the controller has to execute a master task, this state is the start point before enabling a
Tx Header command.
When the controller has only to execute slave tasks, LIN header detection/acquisition is
enabled as background function. At the end of such an acquisition (Rx Header function), auto-
matically the appropriate flags are set, and in LIN 1.3, the LINDLR register is set with the
uncoded length value.
This state is also the start point before enabling the Tx or the Rx Response command.
A running function (i.e. Tx Header, Tx or Rx Response ) can be aborted by clearing
LCMD[1..0] bits in LINCR register
flag - LABORT - in LINERR register will be set to inform the other software tasks. No wait
states are implemented, so, the abort command is taken into account immediately.
Rx Header function is responsible for:
LENA
• The BREAK field detection,
• The hardware re-synchronization analyzing the SYNCH field,
• The reception of the PROTECTED IDENTIFIER field, the parity control and the update of
• The starting of the Frame_Time_Out,
• The checking of the LIN communication integrity.
