BusMatching
LVTTL
This pin is setup before Master Reset and must not toggle during any device operation. This pin is used
INPUT
along with IW and OW to setup the multi-queue flow-control device bus width. Please refer to Table 3
fordetails.
D[35:0]
Data Input Bus
LVTTL
These are the 36 data input pins. Data is written into the device via these input pins on the rising edge
Din
INPUT
ofWCLKprovidedthat
WENisLOW.Note,thatinPacketmodeD32-D35maybeusedaspacketmarkers,
please see packet ready functional discussion for more detail. Due to bus matching not all inputs may be
used, any unused inputs should be tied LOW.
DF(1)
Default Flag
LVTTL
If the user requires default programming of the multi-queue device, this pin must be setup before Master
INPUT
Reset and must not toggle during any device operation. The state of this input at master reset determines
the value of the
PAE/PAF flag offsets. If DF is LOW the value is 8, if DF is HIGH the value is 128.
DFM(1)
Default Mode
LVTTL
The multi-queue device requires programming after master reset. The user can do this serially via the
INPUT
serial port, or the user can use the default method. If DFM is LOW at master reset then serial mode will be
selected, if HIGH then default mode is selected.
ESTR
PAEn Flag Bus
LVTTL
If direct operation of the
PAEn bus has been selected, the ESTR input is used in conjunction with RCLK
Strobe
INPUT
and the RDADD bus to select a sector of queues to be placed on to the
PAEn bus outputs. A sector
addressed via the RDADD bus is selected on the rising edge of RCLK provided that ESTR is HIGH. If
Polled operations has been selected, ESTR should be tied inactive, LOW. Note, that a
PAEn flag bus
selectioncannotbemade,(ESTRmustNOTgoactive)untilprogrammingoftheparthasbeencompleted
and
SENO has gone LOW.
ESYNC
PAEn Bus Sync
LVTTL
ESYNC is an output from the multi-queue device that provides a synchronizing pulse for the
PAEn bus
OUTPUT
duringPolledoperationofthe
PAEnbus.DuringPolledoperationeachsectorofqueuestatusflagsisloaded
on to the
PAEn bus outputs sequentially based on RCLK. The first RCLK rising edge loads sector 1 on

PAEn,thesecondRCLKrisingedgeloadssector2.ThethirdRCLKrisingedgewillagainloadsector1.
During the RCLK cycle that sector 1 of a selected device is placed on to the
PAEnbus,theESYNCoutput
will be HIGH. For sector 2 of that device, the ESYNC output will be LOW.
EXI
PAEnBus
LVTTL
The EXI input is used when multi-queue devices are connected in expansion mode and Polled
PAEn
Expansion In
INPUT
bus operation has been selected . EXI of device ‘N’ connects directly to EXO of device ‘N-1’. The EXI
receives a token from the previous device in a chain. In single device mode the EXI input must be tied
LOW if the
PAEnbusisoperatedindirectmode.IfthePAEnbusisoperatedinpolledmodetheEXIinput
must be connected to the EXO output of the same device. In expansion mode the EXI of the first device
should be tied LOW, when direct mode is selected.

EXO is an output that is used when multi-queue devices are connected in expansion mode and Polled

(token) is then passed on to the next device in the chain ‘N+1’ and on the next RCLK rising edge the first
sector of device N+1 will be loaded on to the
PAEnbus.ThiscontinuesthroughthechainandEXOofthe
last device is then looped back to EXI of the first device. The ESYNC output of each device in the chain
provides synchronization to the user of this looping event.
FF
Full Flag
LVTTL
This pin provides the full flag output for the active queue, that is, the queue selected on the input port for
OUTPUT
write operations, (selected via WCLK, WRADD bus and WADEN). On the WCLK cycle after a queue
selection, this flag will show the status of the newly selected queue. Data can be written to this queue on
the next cycle provided
FF is HIGH. This flag has High-Impedance capability, this is important during
expansionofdevices,whenthe

FFbus,allotherdevicesplacetheirFFoutput
into High-Impedance. When a queue selection is made on the write port this output will switch from
High-Impedance control on the next WCLK cycle. This flag is synchronized to WCLK.
