• Bit 7– Reserved Bit
This bit is reserved for future use. For compatibility with future devices, it must be written to
zero when CANBT3 is written.
• Bit 6:4 – PHS22:0: Phase Segment 2
This phase is used to compensate for phase edge errors. This segment may be shortened by
the re-synchronization jump width. PHS2[2..0] shall be 1 and PHS1[2..0] (c.f.
“CAN Bit Timing” on page 170
• Bit 3:1 – PHS12:0: Phase Segment 1
This phase is used to compensate for phase edge errors. This segment may be lengthened by
the re-synchronization jump width.
• Bit 0 – SMP: Sample Point(s)
This option allows to filter possible noise on TxCAN input pin.
‘SMP=1’ configuration is not compatible with ‘BRP[5:0]=0’ because TQ =
If BRP = 0, SMP must be cleared.
• Bit 7:0 – TPRSC7:0: CAN Timer Prescaler
Prescaler for the CAN timer upper counter range 0 to 255. It provides the clock to the CAN
timer if the CAN controller is enabled.

clocks before the user configured sampling point - SP, again at one
before SP and finally at SP. Then the bit level will be determined by a majority vote
of the three samples.
