DMA Requested number of ele

HI ,

Just a simple question about DMA channel.

When im configuring an taget to host or host to target DMA ,

Data type is U16 , and requested num of elements is 1023 .

does it mean that the whole size of the fifo is 2Kbytes , each cell of the fifo is U16 data (2 bits ) ?

what exactly is element ?

Thank you.
