ID
The header is transmitted as soon as the identifier is written in the LIN Identifier register
(US_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
(US_LINIR). The Identifier parity bits can be automatically computed and sent (see
39.7.8.9).
The flag TXRDY rises when the identifier character is transferred into the Shift Register of the
transmitter.
As soon as the Synch Break Field is transmitted, the flag LINBK in the Channel Status register
(US_CSR) is set to 1. Likewise, as soon as the Identifier Field is sent, the flag LINID in the Chan-
nel Status register (US_CSR) is set to 1. These flags are reset by writing the bit RSTSTA to 1 in
the Control register (US_CR).
