MAX((A), (M)) ⇒ A
MAXA
MAX of 2 Unsigned 8-Bit Values
N, Z, V and C status bits reflect result of
internal compare ((A) – (M)).
MAX((A), (M)) ⇒ M
MAXM
MAX of 2 Unsigned 8-Bit Values
N, Z, V and C status bits reflect result of
internal compare ((A) – (M)).
µ (grade) ⇒ M
MEM
(X) + 4 ⇒ X; (Y) + 1 ⇒ Y; A unchanged
if (A) < P1 or (A) > P2 then µ = 0, else
µ = MIN[((A) – P1)×S1, (P2 – (A))×S2, $FF]
where:
A = current crisp input value;
X points at 4-byte data structure that de-
scribes a trapezoidal membership function
(P1, P2, S1, S2);
Y points at fuzzy input (RAM location).
See instruction details for special cases.
