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 accessible in Configuration mode only.
