DS. Data Strobe (Output, default active High): The
strobe pin enables the user to utilize the output.
When this pin is High it indicates that a new output
variable has been calculated and it is ready on the
output bus (O0-O7). This signal synchronizes the
external devices and in particular the interfaces
with the controlled processes (On-Line mode).
ERR. Error (Output, active Low): When this pin is
active, W.A.R.P.2.0 has incurred in an internal error
condition.
OC0-OC1. Output Counter (Output): This 2 bit
output bus provides the output variables with a
progressive number during the On-Line phase. As
a consequence it is possible to know to which
variable correspond the data that are on the output
data bus (O0-O7). The dimension of OC bus is
connected with the maximum number of output
variables (4).
O0-O11. Output Bus (Output): In the Off-Line
phase these pins provide the addresses (12 bit) for
its internal memories and send those addresses to
the external memory support where data to load are
located. These addresses sent on O0-O11 bus
allow to identify the data that have to be loaded in
W.A.R.P.2.0 internal memories.
In the On-Line phase O0-O7 carrie out the output
values. When the DS is High, one output variable
can be read by external devices. The resolution
of output variables is 256 points (8 bit). If there is
more than one output, the output variables are
calculated one by one and they are provided in
the sequence stabilized during the editing phase
(see FUZZYSTUDIO™ 2.0 User Manual).
In On-Line mode O8-O10 provide the progressive
number of the next variable to be acquired. These
pins can be used to select the next input to provide
on I0-I7 bus.
Still in on-line mode O11 allows to provide a preset-
table signal which can be used as Start-Conversion
for an A/D converter after (about 400 ns) OFL or
BUSY fall.
