The contents of Bus Timing Register 1 defines the length
of the bit period, the location of the sample point and the
number of samples to be taken at each sample point.

Sampling. If the bit SAM is:
TSEG1 determines the number of clock cycles per bit period and the location of the sample point
TSEG2 determines the number of clock cycles per bit period and the location of the sample point:

HIGH (3 samples), then three samples are taken. This is recommended for slow/medium speed
buses (SAE class A and B) where filtering of spikes on the bus-line is beneficial
(see Section 13.5.19.6)
LOW (1 sample), the bus is sampled once.
This is recommended for high speed buses (SAE class C).
