7.3 Signal definitions
The pin assignments of interface signals are listed as follows:Signal definitions
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.
