Double word move to/from periph registers when using the DMA

From what I understand, the c55x dma is designed to always move 4 bytes (two words) of data.  When the dma configuration source or destination address is a periph in I/0 space, does the dma read/write data to the base i/o address as well as the i/o space at the next higher address?

For example on the 5535, if my source address is I2S0RXLT0 (I2S0 Receive Left data 0 Register) at i/o address 0x2828, when the dma reads from this base address and transfers two words into the destination, does it also transfer the value in I2S0RXLT1 at i/o address 0x2829?

thanks
