BTR0 defines the value of the Re-synchronization Jump Width (SJW) and the Baud Rate Prescaler (BRP). This register can be read
anytime and written only in init mode (MODE<2:0> bits set to <1xx> in the CTRL0 register).

Re-synchronization Jump Width bits <1:0>.
These bits are used to compensate for phase shifts between different clock oscillators on the
bus. They define the maximum number of time quanta (Tq) a bit can be shortened or
lengthened to allow a node achieve re-synchronization to the edge of an incoming signal.
Note that one time quantum (Tq) is the single unit of time within a bit time (see Bit Timing
section).
Note:
Baud Rate Prescaler bits <5:0>.
The baud rate prescaler relates the system oscillator frequency, f
described in the bit timing section.
ARINC 825 states that the Re-synchronization Jump Width shall be 1 Tq
