3.19
This mode is currently used by the DVC 8-Bit DMA and 8/16-Bit DMA modes. In the DVC 8-Bit DMA mode, the DMA data path
will be 8-bits, which correspond to SD0-SD7. In the 8/16-Bit DMA mode, the DMA data path can be configured to either 8 or 16 bits.
3.20
The SL11R has four modes. They are: General Purpose I/O mode, Fast EPP mode, 8-bit DMA mode, and 8/16-bit DMA Mailbox
Protocol ports mode. These modes are shared and can be configured under software control.
Note: The UART and 2-wire serial interface I/O pins are fixed in all cases.
