Dear Adrian,

Yes, that is correct. It relates to the AHB bus DMA burst size.

    /*
     * Split data into chunks of 16 or 8 bytes for sending.
     * Each chunk transfer is guaranteed to be uninterrupted on the bus.
     * This likely corresponds to the AHB bus DMA burst size.
     */

Best Regards,

Shan-Chun
