PRODUCT SPECIFICATION
REV. 1.0.2 10/25/00
7
Notes:
1. The output ports X, Y, Z and CASOUT, and input port CASIN are internally reconfigured by the device as required for each
mode of the device. The multiple-function pins have names which are combinations of these titles, as appropriate.
2. The output drivers on pins XC
11-0
and YC
11-8
are not necessarily disabled until after the first rising edge of CLK following
power-up. If these pins are to be tied to other output drivers, to each other, or to ground or V
DD
, the user should ensure that
a clock pulse arrives within a few seconds of power-up, to avoid bus contention.

Output X
XC
11-0
In all modes except Mode 00, the x port and four bits
of the Y output port are reconfigured as the 16-bit
registered Cascade Input port CASIN
15-0
. Data
presented to this input will be added to the weighted
sums of the data words which were presented to the
input ports (A, B and C).
In the matrix multiply mode, data are available at the
12-bit registered output ports X, Y AND Z t
DO
after
every clock. These ports are reconfigured in the
filtering modes as 16-bit Cascade Input and Output
ports.CASOUT

In all modes except Mode 00, the Z port and four bits
of the Y output port are reconfigured as the 16-bit
