This field indicates the number of bytes to transfer to or from the appropriate PIO register in the UART4
device HW_UARTAPP_DATA. A value of 0 indicates a 64 KBytes transfer.
This field indicates the number of command words to send to the UART, starting with the base PIO address
of the UART4 (HW_UARTAPP_CTRL0) and increment from there. Zero means transfer NO command
words
