- Each CAN-bit is broken up into 4 non-overlapping segments.

 - t_NBT = t_{SYNC_SEG} + t_{PROP_SEG} + t_{PHASE_SEG1} + t_{PHASE_SEG2}

 - Each of these segments is an integer multiple of a unit of time called a Time Quantum.

 - The duration of a Time Quantum is equal to the period of the CAN system clock, which is derived from the microcontroller (MCU) system clock or oscillator by way of a programmable prescaler, called the Baud Rate Prescaler.

 - The lengths of these segments are set during the CAN initialization/configuration.

 - The CAN controller samples each CAN-bit on the bus at the Sample Point.

 - The CAN bit sample point is between tPHASE_SEG1 and tPHASE_SEG2.

 - Valid range for location of sample point is from 75% to 90%.

 - Note*: Use sample points of 80% to 90%.

 - Recommended location of sample point is 87,5%.
