12.3.3
In LIN operating mode (BTM = 0), the SLCBT is updated by the SLIC upon reception of a LIN break-sync
combination and provides the number of SLIC clock counts that equal one LIN bit time to the user
software. This value can be used by the software to calculate the clock drift in the oscillator as an offset to
a known count value (based on nominal oscillator frequency and LIN bus speed). The user software can
then trim the oscillator to compensate for clock drift. Refer to
SLIC,” for more information on this procedure. The user should only read the bit time value from
SLCBTH and SLCBTL in the interrupt service routine code for reception of the identifier byte. Reads at
any other time during LIN activity may not provide reliable results.
When in byte transfer mode (BTM = 1), the SLCBT must be written by the user to set the length of one
bit at the desired bit rate in SLIC clock counts. The user software must initialize this number prior to
sending or receiving data, based on the input clock selection, prescaler stage choice, and desired bit rate.
This setting is similar to choosing an input capture or output compare value for a timer. A write to both
registers is required to update the bit time value.

SLIC Bit Time Registers (SLCBTH, SLCBTL)
Digital RX Filter
Clock Prescaler
In this subsection, the SLIC bit time registers are collectively referred to as
SLCBT.
The SLIC bit time will not be updated until a write of the SLCBTL has
occurred.
