bit 2-0

SEG2PHTS: Phase Segment 2 Time Select bit

1 = Freely programmable

0 = Maximum of PHEG1 or Information Processing Time (IPT), whichever is greater

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

SEG1PH2:SEG1PH0: Phase Segment 1 bits

111 = Phase Segment 1 Time = 8 x TQ

110 = Phase Segment 1 Time = 7 x TQ

101 = Phase Segment 1 Time = 6 x TQ

100 = Phase Segment 1 Time = 5 x TQ

011 = Phase Segment 1 Time = 4 x TQ

010 = Phase Segment 1 Time = 3 x TQ

001 = Phase Segment 1 Time = 2 x TQ

000 = Phase Segment 1 Time = 1 x TQ

PRSEG2:PRSEG0: Propagation Time Select bits

111 = Propagation Time = 8 x TQ

110 = Propagation Time = 7 x TQ

101 = Propagation Time = 6 x TQ

100 = Propagation Time = 5 x TQ

011 = Propagation Time = 4 x TQ

010 = Propagation Time = 3 x TQ

001 = Propagation Time = 2 x TQ

000 = Propagation Time = 1 x TQ

Legend:

R = Readable bit

- n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown

Note: This register is only accessible in Configuration mode.
