Three registers are used internally to manage the auto-update of the LIN divider (LDIV):
The control and interactions of these registers is explained in
depends on the LDUM bit setting (LIN divider update method)
As explained in
transfer from LDIV_MEAS at the end of the LIN sync field and a transfer from LDIV_NOM
due to a software write of LPR. If both operations occur at the same time, the transfer from
LDIV_NOM has priority.
