-HDMARDY (Ultra DMA)
This signal is used only for Ultra DMA data transfers between host and drive.
The signal -HDMARDY is a flow control signal for Ultra DMA data in bursts. This signal is held asserted by the
host to indicate to the device that the host is ready to receive Ultra DMA data in transfers. The host may negate
-HDMARDY to pause an Ultra DMA data in transfer.
HSTROBE (Ultra DMA)
This signal is used only for Ultra DMA data transfers between host and drive.
The signal HSTROBE is the data out strobe signal from the host for an Ultra DMA data out transfer. Both the
rising and falling edge of HSTROBE latch the data from DD (15:0) into the device. The host may stop toggling
HSTROBE to pause an Ultra DMA data out transfer.
STOP (Ultra DMA)
This signal is used only for Ultra DMA data transfers between host and drive.
The STOP signal shall be asserted by the host prior to initiation of an Ultra DMA burst. A STOP shall be negated
by the host before data is transferred in an Ultra DMA burst. Assertion of STOP by the host during or after data
transfer in an Ultra DMA mode signals the termination of the burst.
-DDMARDY (Ultra DMA)
This signal is used only for Ultra DMA data transfers between host and drive.
The signal -DDMARDY is a flow control signal for Ultra DMA data out bursts. This signal is held asserted by the
device to indicate to the host that the device is ready to receive Ultra DMA data out transfers. The device may
negate -DDMARDY to pause an Ultra DMA data out transfer.
DSTROBE (Ultra DMA)
This signal is used only for Ultra DMA data transfers between host and drive.
The signal DSTROBE is the data in strobe signal from the device for an Ultra DMA data in transfer. Both the
rising and the falling edge of DSTROBE latch the data from DD (15:0) into the host. The device may stop
toggling DSTROBE to pause an Ultra DMA data in transfer.
