pin in order to start EPROM programming. A signal
applied to PB1 is used to increment the memory
address; the data is supplied to PORT A (see
EPROM programming for further details).
1.2.2 Working mode.
Below are the control signals of this mode:
The processor starts the working phase following
the instructions, which have been previously
loaded in the memory.

The CU/DPU can manage up to 334 different
Members hip Functions for the fuzzy rules
antecedent part. The rule consequents are “crisp”
values (real numbers). The maximum number of
rules that can be defined is limited by the
d i m e n s i o n s o f t h e i m p l e m e n t e d s t a n d a r d
algorithm.
EPROM is then shared between fuzzy and
standard algorithms. The Membership Function
data is stored inside the first 1024 memory
locations. The Fuzzy rules are parts of the program
instructions.
The Control Unit (CU) reads the information and
the status deriving from the peripherals.
Arithmetic calculus can be performed on these
values by using the internal CU and the 128/256
bytes of RAM, which supports all computations.
The peripheral input can be fuzzy and/or arithmetic
output, or the values contained in Data RAM and
EPROM locations.
