3.12 True IDE Multiword DMA Mode Read/Write Timing Specification

The timing diagram for True IDE DMA mode of operation in this section is drawn using the conventions in the ATA-4 specification. Signals are shown with their asserted state as high regardless of whether the signal is actually negative or positive true. Consequently, the -IORD, the -IOWR and the -IOCS16 signals are shown in the diagram inverted from their electrical states on the bus.
