This field contains the current number of bytes still to be transferred for this buffer.
This field is decremented at each dma access.
This field is reliable (stable) only if the CHEN bit is zero.
This bit is set when a Descriptor has been loaded from the HSB bus.
This bit is cleared when read by the user.
This bit is set when the Channel Byte Count counts down to zero.
This bit is automatically cleared when read by software.
This bit is set when the completion of the usb data transfer has closed the dma transfer. It is valid only if
This bit is automatically cleared when read by software.
0: the DMA channel is no longer trying to source the packet data.

When programming a DMA by descriptor (Load next descriptor now), the CHACTIVE bit is set only once the DMA is running
This bit is set (after one cycle latency) when the L.CHEN is written to one or when the descriptor is loaded.
This bit is cleared when any transfer is ended either due to an elapsed byte count or a USB device initiated transfer end.
0: the DMA channel no longer transfers data, and may load the next descriptor if the UDDMAnCONTROL.LDNXTCHDESCEN
