|
19 | GND | Digital Ground |
20 | Key/GND | Key pin plug/Ground |
21 | PDRQ | DMA Request – Used for DMA transfers between host and drive (direction of |
|
| transfer controlled by PIOR* and PIOW*). Also used in an asynchronous mode |
|
| with PDACK*. Drive asserts PIRQ when ready to transfer or receive data. |
22 | GND | Digital Ground |
23 | PIOW* | Drive I/O Write – Strobe signal for write functions. Negative edge enables data |
|
| from a register or data port of the drive onto the host data bus. Positive edge |
|
| latches data at the host. |
24 | GND | Digital Ground |
