// This code is a hardware specific device driver for the SoRo Systems

|
|
// USB-D12-104, a PC/104 (ISA) Full-Speed USB slave board, which turns
|
| 49 |
|
|
// a PC/104 stack into a USB slave device. The board contains a
|
| 50 |
|
|
// Philips PDIUSBD12 Peripheral Controller Chip mapped into the PC's
|
| 51 |
|
|
// I/O space, with jumper-selectable I/O base address, IRQ, and DMA
|
| 52 |
|
|
// settings. The eCos config tool is used to adjust settings for this
|
| 53 |
|
|
// driver to match the physical jumper settings. The chip could run in
|
| 54 |
|
|
// polled mode without an IRQ, but this wouldn't be a great idea other
|
| 55 |
|
|
// than maybe a debug environment.
