Note:
Bit 4 = LASE LIN Auto Synch Enable.
This bit enables the Auto Synch Unit (ASU). It is set and cleared by software. It is only
usable in LIN Slave mode.
Bit 3 = LHDM LIN Header Detection Method
This bit is set and cleared by software. It is only usable in LIN Slave mode. It enables the
Header Detection Method. In addition if the RWU bit in the
SCICR2 register is set, the LHDM bit selects the Wake-Up method (replacing the WAKE bit).
Bit 2 = LHIE LIN Header Interrupt Enable
This bit is set and cleared by software. It is only usable in LIN Slave mode.
Bit 1 = LHDF LIN Header Detection Flag
This bit is set by hardware when a LIN Header is detected and cleared by a software
sequence (an access to the SCISR register followed by a read of the SCICR3 register). It is
only usable in LIN slave mode.
The header detection method depends on the LHDM bit:
- If LHDM = 0, a header is detected as a LIN synch break.
- If LHDM = 1, a header is detected as a LIN Identifier, meaning that a LIN synch
break field + a LIN synch field + a LIN identifier field have been consecutively received.
Bit 0 = LSF LIN Synch Field State
This bit indicates that the LIN synch field is being analyzed. It is only used in LIN slave
mode. In auto synchronization mode (LASE bit = 1), when the SCI is in the LIN synch field
State it waits or counts the falling edges on the RDI line.
It is set by hardware as soon as a LIN synch break is detected and cleared by hardware
when the LIN synch field analysis is finished (see
software to exit LIN synch state and return to idle mode.
