Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7
SEG2PHTS: Phase Segment 2 Time Select bit
1 = Freely programmable
0 = Maximum of PHEG1 or Information Processing Time (IPT), whichever is greater
bit 6
SAM: Sample of the CAN bus Line bit
1 = Bus line is sampled three times prior to the sample point
0 = Bus line is sampled once at the sample point
