• Message Transmission Request
The following sequence is an example to transmit a CAN frame onto the bus. As described in the
previous register section, please note that IRR8 is set when one of the TXACK or ABACK bits is
set, meaning one of the Mailboxes has completed its transmission or transmission abortion and is
now ready to be updated for the next transmission, whereas, the GSR2 means that there is
currently no transmission request made (No TXPR flags set).
• Internal Arbitration for transmission
The following diagram explains how RCAN-TL1 manages to schedule transmission-requested
messages in the correct order based on the CAN identifier. ‘Internal arbitration’ picks up the
highest priority message amongst transmit-requested messages.
