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 GPMI6
device HW_GPMI_DATA register. A value of 0 indicates a 64 Kbytes transfer.
This field indicates the number of command words to send to the GPMI6, starting with the base PIO
address of the GPMI6 (HW_GPMI_CTRL0) and increment from there. Zero means transfer NO
