Description
DMA Request A. This signal is the primary port DMA handshake
from the IDE device. When asserted, it indicates a data transfer is
requested.
DMA Acknowledge A. This is the primary port DMA handshake to
the IDE device. When asserted, it indicates a data transfer can be
executed.
DMA Request B. This is the secondary port DMA handshake from
the IDE device. When asserted, it indicates a data transfer is
requested.
DMA Acknowledge B. This is the secondary port DMA handshake
to the IDE device. When asserted, it indicates a data transfer can be
executed.
IDE Drive Address.
IDE Drive Data. 16-bit bi-directional bus.
