32 IOCS16B
O
During PIO transfer mode 0, 1 or 2, this pin indicates to
the host the 16-bit data port has been addressed and the
device is prepared to send or receive a 16-bit data word.
When transferring in PIO mode 3, 4, or above, this signal
should not be used by the host, and all transfers will be
16-bit. When transferring in DMA mode, the host must
use a 16-bit DMA channel and this signal will not be
asserted.
35, 33, 36 DA0 ~ DA2 (Device
Address)
I
This is the 3-bit binary coded Address Bus.
-PDIAG (Passed
diagnostics)
34
-CBLID (Cable assembly
type identifier)
I/O
This signal will be asserted by Device 1 to indicate to
Device 0 that Device 1 has completed diagnostics.
37, 38 -CS0, -CS1 (Chip select)
I
These signals are used to select the Command Block
and Control Block registers. When –DMACK is asserted,
-CS0 and –CS1 shall be negated and transfers shall be
16-bit wide.
39 -DASP (Device active,
Device 1 present)
I/O
During the reset protocol, -DASP shall be asserted by
Device 1 to indicate that the device is present.
41, 42 VCC

* Note:
“I” An input from the host system to the device.
“O” An output from the device to the host system.
“I/O” An input/output (bi-direction) common.
“P” Power supply.
