BTLMODE: Phase Segment 2 Bit Time Length
1 = Length of Phase Seg 2 determined by PHSEG22:PHSEG20 bits of CNF3
0 = Length of Phase Seg 2 is the greater of Phase Seg 1 and IPT (2T
SAM: Sample Point Configuration
1 = Bus line is sampled three times at the sample point
0 = Bus line is sampled once at the sample point
