(1) SJW bits (D0-D1)
These bits set reSynchronization Jump Width.
(2) PH2 bits (D2-D4)
These bits set the width of Phase Segment2.
Note: The internal CAN module of the M32R/E has IPT (Information Processing Time) = 2.
Because PH2 bits = 0 after reset, be sure to change it to a value equal to or greater than 2
before you use the CAN module.
(3) PH1 bits (D5-D7)
These bits set the width of Phase Segment1.
(4) PRB bits (D8-D10)
These bits set the width of Propagation Segment.
(5) SAM bit (D11)
This bit sets the number of times each bit is sampled. When SAM = 0, the value sampled at the
end of Phase Segment1 is assumed to be the value of the bit. When SAM = 1, the value of the bit
is determined by a majority circuit from values sampled at three points-one sampled at the end of
Phase Segment1, one sampled before 1Tq, and one sampled before 2Tq.
