HDD15-0
I/O
IDE device data. The 8- or 16-bit data bus to/from the ATA device.
Only the lower 8 bits are used for 8-bit register transfers.
44
HDIORDY(D
DMARDY#/,
DSTROBE)
I
I/O channel ready (for PIO and Multi-word DMA mode)
Ultra DMA device ready (for UDMA write)
Ultra DMA device data strobe (for UDMA read)
42
HDINT
I
IDE device interrupt: This input signal is used to interrupt the host
system when interrupt pending is set.
43
HDDACK# O
IDE DMA acknowledge: This signal is used by the ATA host to
response DMARQ for DMA transfers.
47
HDDRQ
I
IDE DMA request: This signal is asserted by the ATA device when it
is ready to perform a DMA data transfer to or from the ATA host
when a DMA operation has been enabled.
Signals for PHY-interface
15,16
PHY_CTL1
PHY_CTL0
I/O
Control 1 and Control 0 of the phy-link control bus. CTL1 and CTL0
indicate the four operations that can occur in this interface.
18
LREQ
O
Link request. LREQ is a output that makes bus requests and accesses
the phy layer.
6-9,11-14 PHY_D7-0
I/O
Phy data7 through data0 of the phy-link data bus. Data is expected on
D0-D1 for 100Mb/s packets, D0-D3 for 200Mb/s, and D0-D7 for
400Mb/s.
17
PHY_SCLK
I
System clock. PHY_SCLK is a 49.152-MHz clock from the phy.
