| 1410 The host interface model on FC Venus will need to follow that of section 1.12. | |
| 1411 More specifically, our Venus board will implement the mobile side of the "wall" | |
| 1412 between USB and mobile power domains, complete with all provisions of section | |
| 1413 1.12.2 for the mobile side, whereas the USB domain is already implemented on our | |
| 1414 DUART28 adapter board. The two domains will be interconnected with a ribbon | |
| 1415 cable in the FC Venus lab bench setup. The 10-pin DUART header will have our | |
| 1416 standardized FreeCalypso DUART pinout. | |
| 1417 | |
| 1418 Also following the principal design of section 1.12.3, there will be a 3-pin | |
| 1419 header on the Venus board bringing out RPWON, nTESTRESET and GND, to be | |
| 1420 connected to the boot control header on DUART28C. |
