Header Transmission (Master Node Configuration)
ID
13 dominant bits (at 0)
All the LIN Frames start with a header which is sent by the master node and consists of a Synch
Break Field, Synch Field and Identifier Field.
So in Master node configuration, the frame handling starts with the sending of the header.
The header is transmitted as soon as the identifier is written in the LIN Identifier register (LINIR).
At this moment the flag TXRDY falls.
The Break Field, the Synch Field and the Identifier Field are sent automatically one after the
other.
The Break Field consists of 13 dominant bits and 1 recessive bit, the Synch Field is the charac-
ter 0x55 and the Identifier corresponds to the character written in the LIN Identifier Register
(LINIR). The Identifier parity bits can be automatically computed and sent (see
19.6.5.8).
The flag TXRDY rises when the identifier character is transferred into the Shift Register of the
transmitter.
