446 * A limitation in DMA mode is that the FIFO must be accessed in 4 byte chunks.
461 * stream of 4 byte chunks, it treats every entry separately: A TX entry is
468 * The residue of 1 byte in the RX FIFO is picked up by DMA. Together with
1091 * there is 1 idle clocks cycles after each byte getting transferred
1092 * so we have 9 cycles/byte. This is used to find the number of Hz
1093 * per byte per polling limit. E.g., we can transfer 1 byte in 30 us
