(please refer to the ata / atapi-6 specification rev 1.0 for more information.) - ultra dma: ultra dma is a data transfer protocol used with the read dma, write dma, read dma queued, write dma queued and packet commands. when this protocol is enabled, the ultra dma protocol shall be used instead of the multiword dma protocol when these commands are issued by the host. this protocol applies to the ultra dma data burst only. (please refer to the ata / atapi-6 specification rev 1.0 for more information.) following listed the symbols and their respective definitions that are used in the timing diagram:
GL811USB ? usb 2.0 to ata / atapi bridge controller ?2000-2002 genesys logic inc.?all rights reserved. page 14 all signals are shown with the asserted condition facing to the top of the page. the negated condition is shown towards the bottom of the page relative to the asserted condition. the interface uses a mixture of negative and positive signals for control and data. the terms asserted and negated are used for consistency and are independent of electrical characteristics. in all timing diagrams, the lower line indicates negated, and the upper line indicates asserted. the following illustrates the representation of a signal named test going from negated to asserted and back to negated, based on the polarity of the signal. - signal transition (asserted or negated) - data transition (asserted or negated) - data valid - undefined but not necessarily released - asserted, negated or released - released - the ?other? condition if a signal is shown with no change assert assert negate negate te s t te s t _ > v ih < v il < v il > v ih
