BTL MODE: Length determination of PHSEG2 bit
1 = Length of Phase_Seg2 determined by bits 2:0 of CNF3
0 = Length of Phase_Seg2 is the greater of Phase_Seg1 or IPT(2Tq)
SAM: Sample of the CAN bus line bit
1 = Bus line is sampled three times at the sample point
0 = Bus line is sampled once at the sample point
