8 / 88 page ST52T430/E430 8/88 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. S T 52 x 4 3 0 ’ s i n t e rna l s t ruc t ure i n c l ud es a computational block, CONTROL UNIT (CU) / DATA PROCESSING UNIT (DPU), which allows pro ces sin g of b oo le an fu ncti on s an d fuzz y algorithms. The CU/DPU can manage up to 334 different M e m bersh i p F unc ti ons fo r the f u zz y ru l e s antecedent part. The rule consequents are “crisp” values (real numbers). The maximum number of rul es that ca n be defined i s l im ited by th e di m e n s i o n s of the i m pl em e n t e d s t a n d a r d algorithm. EPR OM i s th en sh are d be tw ee n fuzzy an d standard algorithms. The Membership Function data is stored inside the fi rst 1024 mem ory 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.
