The time measurement is made by a 19-bit counter clocked by the sampling clock (see
25.6.1).
When the start bit of the Synch Field is detected the counter is reset. Then during the next 8
Tbits of the Synch Field, the counter is incremented. At the end of these 8 Tbits, the counter is
stopped. At this moment, the 16 most significant bits of the counter (value divided by 8) gives the
new clock divider (LINCD) and the 3 least significant bits of this value (the remainder) gives the
new fractional part (LINFP).
Once the Synch Field has been entirely received, the clock divider (LINCD) and the fractional
part (LINFP) are updated in the LIN Baud Rate register (LINBRR) with the computed values, if
the synchronization is not disabled by the bit SYNCDIS in the LIN Mode register (LINMR).
If after reception of the Synch Field, it appears that the computed baudrate deviation compared
to the initial baud rate is superior to the maximum tolerance FToI_Unsynch (+/- 15%) then the
clock divider (LINCD) and the fractional part (LINFP) are not updated and the error bit STE in the
Channel Status register CSR is set to 1.
If after reception of the Synch Field, it appears that the sampled Synch character is not equal to
0x55 then the clock divider (LINCD) and the fractional part (LINFP) are not updated, and the
error bit ISFE in the Channel Status register (CSR) is set to 1.
The bits LINSTE and LINISFE are reset by writing the bit RSTSTA at 1 in the Control register
(CR).
The accuracy of the synchronization depends on several parameters:
The following formula is used to compute the deviation of the slave bit rate relative to the master
bit rate after synchronization (F
• The nominal clock frequency (F
• The Baudrate
• The oversampling (Over=0 => 16X or Over=0 => 8X)
