Example 1:
IF Input
is codified by the following instructions:
LDN 1 1
LDP 4 12
FZAND
LDK
LDP 3 8
FZOR
LDP
CON crisp
Example 2, the priority of the operator is fixed by the brackets:
IF (Input
LDP 3
LDN 4 15
FZAND
LDP 1 6
LDN 2 14

CON crisp
At the end of the fuzzy rule, by using the instruction OUT RAM_reg, a byte is written. Afterwards, the con-
trol of the algorithm goes returns to the CU.
