Note
1. The Test Register is used for production testing only.
13.5.3
The contents of the Control Register are used to change the behaviour of the CAN-controller. Control bits may be set or
reset by the CPU which uses the Control Register as a read/write memory.

HIGH (enabled), then the CAN-controller enters Test Mode (normal operations
impossible).
LOW (disabled), then the CAN-controller is in normal operating mode.
HIGH (2 edges), then bus-line transitions from recessive-to-dominant and vice-versa
are used for resynchronization (see Sections 13.5.20 and 13.6).
LOW (1 edge), then the only transitions from recessive-to-dominant are used for
resynchronization.
