Programmable Registers
The command register controls the overall operation of each DMA command for this channel.
It includes the number of bytes to transfer to or from the device, the number of APB PIO
command words included with this command structure, whether to interrupt at command
completion, whether to chain an additional command to the end of this one and whether
this transfer is a read or write DMA transfer.

This field indicates the number of bytes to transfer to or from the appropriate PIO register in the UART1
device HW_UARTAPP_DATA register. A value of 0 indicates a 64 KBytes transfer.
This field indicates the number of command words to send to the UART2, starting with the base PIO address
of the UART2 (HW_UARTAPP_CTRL1) and increment from there. Zero means transfer NO command
words
Reserved, always set to zero.
A value of one indicates that the channel will wait for the end of command signal to be sent from the APBX
device to the DMA before starting the next DMA command.
