Bits 7:6 – ABW[1:0]: Auto-Baud Window Size

Auto-Baud Window Size

These bits control the tolerance for the difference between the baud rates between the two synchronizing devices when using Lin Constrained Auto-baud mode. The tolerance is based on the number of baud samples between every two bits. When baud rates are identical, there must be 32 baud samples between each bit pair since each bit is sampled 16 times.
