Notes:
1. "O" designates an output from the Drive.
2. "I" designates an input to the Drive.
3. "I/O" designates an input/output common.
4. "OD" designates an Open-Drain output.
5. The signal lines marked with (*) are redefined during the Ultra DMA protocol to provide special
functions. These lines change from the conventional to special definitions at the moment the Host
decides to allow a DMA burst, if the Ultra DMA transfer mode was previously chosen via
SetFeatures. The Drive becomes aware of this change upon assertion of the -DMACK line. These
lines revert back to their original definitions upon the deassertion of DMACK at the termination of
the DMA burst.
6. "power" designates a power supply to the drive.
7. "reserved" designates reserved pins which must be left unconnected.
