Ultra DMA (Direct Memory Access) Mode
This feature allows the user to select Ultra DMA Modes. DMA Modes allow peripheral devices (such as sound cards, floppy disks) transfer data directly to and from memory without going through the CPU. With double transition clocking, UDMA (Ultra DMA) allows data to be transferred on both the rising and the falling edges of the clock, doubling data throughput for any given clock speed. The options are Disabled, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4, and Mode 5. Please refer to the table below for detailed information.
Ultra DMA Mode | Cycle Time |
| (Nanoseconds) |
Mode 0 | 240 |
Mode 1 | 160 |
Mode 2 | 120 |
Mode 3 | 90 |
Mode 4 | 60 |
Mode 5 | 40 |
