Each Transmit Buffer has its own Add Request bit. Writing a ‘1’ will set the corresponding Add Request bit; writing a ‘0’ has no impact. This enables the processor to set transmission requests for multiple Transmit Buffers with one write to MCAN_TXBAR. MCAN_TXBAR bits are set only for those Transmit Buffers configured via TXBC. When no Transmit scan is running, the bits are reset immediately, else the bits remain set until the Transmit scan process has completed.
