The following is an example to transmit a CAN frame onto the bus. Note that IRR8 is set when
one of the CANTXACK or CANABACK bits is set, meaning one of the Mailbox has
completed its transmission or transmission abortion and is now ready to be updated for the
next transmission, whereas the GSR3 means that there is currently no transmission request
made (CANTXPR = H'0000).
The following diagram explains how HCAN2 manages to schedule transmission-requested
messages in the correct order based on the CAN identifier. ‘Internal arbitration' picks up the
highest priority message among messages transmitted-request messages.
