to be written to can be selected via WCLK, WADEN and the WRADD address bus regardless of the
The WEN input enables write operations to a selected queue based on a rising edge of WCLK. A queue
state of WEN. Data present on Din can be written to a newly selected queue on the second WCLK cycle
after queue selection provided that WEN is LOW. A write enable is not required to cycle the PAFn bus
(in polled mode) or to select the device , (in direct mode).
For the 8Q device the WRADD bus is 6 bits. The WRADD bus is a dual purpose address bus. The first
function of WRADD is to select a queue to be written to. The least significant 3 bits of the bus, WRADD[2:0]
are used to address 1 of 8 possible queues within a multi-queue device. The most significant 3 bits,
WRADD[5:3] are used to select 1 of 8 possible multi-queue devices that may be connected in expansion
mode. These 3 MSb’s will address a device with the matching ID code. The address present on the WRADD
bus will be selected on a rising edge of WCLK provided that WADEN is HIGH, (note, that data present on
the Din bus can be written into the previously selected queue on this WCLK edge and on the next rising
WCLK also, providing that WEN is LOW). Two WCLK rising edges after write queue elect, data can be
written into the newly selected queue.
The second function of the WRADD bus is to select the device of queues to be loaded on to the PAFn bus
during strobed flag mode. The most significant 3 bits, WRADD[5:3] are again used to select 1 of 8 possible
multi-queue devices that may be connected in expansion mode. Address bits WRADD[2:0] are don’t care
during device selection. The device address present on the WRADD bus will be selected on the rising
edge of WCLK provided that FSTR is HIGH, (note, that data can be written into the previously selected
queue on this WCLK edge). Please refer to Table 1 for details on the WRADD bus.
