Notes: • Do not change settings of the CAN Configuration Register (CAN0CONF or CAN1CONF) during CAN operation (CAN
Status Register CRS bit = "0").
• When setting the bits in this register, make sure the conditions given below are met:
• Number of Tq’s for one bit: 8–25 Tq’s
• SJW
≤
min (Phase Segment1, Phase Segment2)
• Phase Segment2 = max (Phase Segment1, IPT) where IPT = 1 for the internal CAN modules of the 32180
min() is the function that returns the smaller of two values; max() is the function that returns the maximum value.
