Nominal and Data Bit Rates
In this section, the nominal and data bit rates for all 6 CAN channels
are configured separately by setting the register values. The
number at the end of the keyword indicates the CAN channel.
CAN_BITRATE_CAN1= f_clock=80000000, nom_brp=1,
nom_tseg1=63, nom_tseg2=16, nom_sjw=16, data_brp=1,
data_tseg1=15, data_tseg2=4, data_sjw=4
When configuring bit rates all register values should be specified. A
default value is used if a single register value is not set. This can
lead to unintended bit rate settings.
