Bits 15:0 – BAUD[15:0] Baud Rate Value

Arithmetic Baud Rate Generation (CTRLA.SAMPR[0]=0):

These bits control the clock generation, as described in the SERCOM Baud Rate section.

If Fractional Baud Rate Generation (CTRLA.SAMPR[0]=1 or =3) bit positions 15 to 13 are replaced by FP[2:0] Fractional Part:

  • Bits 15:13 - FP[2:0]: Fractional Part

    These bits control the clock generation, as described in the section.

  • Bits 12:0 - BAUD[12:0]: Baud Value

    These bits control the clock generation, as described in the section.
