Measured from CAN bit sample
point. Device is a receiver.
Note 1:
All CLKOUT mode functionality and output frequency is tested at device frequency limits, however, CLKOUT prescaler
is set to divide by one. This parameter is periodically sampled and not 100% tested.
2:
Design guidance only, not tested.
