/* LIN Packet Format:
_________ __________ _________ ____________ __________
| | | | ||| |
| Break |Sync 0x55 |PID byte |Data Bytes |||Checksum |
|_________|__________|_________|___________|||_________|
Every byte has start bit and stop bit and it is send LSB first.
Break - 13 bits of dominant state ("0"), followed by 1 bit recesive state ("1")
Sync Byte - Byte for Bound rate syncronization, always 0x55
ID Byte - consist of parity, length and address; parity is determined by LIN standard and depends from address and
message length Data Bytes - user defined; depend on devices on LIN bus Checksum - inverted 256 checksum; data bytes
are summed up and then inverted
