The DCAN module provides several test modes which are mainly intended for production tests or self test.
For all test modes, the DCAN_CTL[7] TEST bit needs to be set to 1. This enables write access to the test register (DCAN_TEST).
It must be ensured by software that all message transfers are completed before entering test mode.
