Tri-level Logic
With binary logic, four states can be programmed with two
control lines, whereas Tri-level Logic can program nine logic
states using two control lines. Tri-level Logic in the SM560 is
implemented by defining a third logic state in addition to the
standard logic “1” and “0.” Pins 6 and 7 of the SM560
recognize a logic state by the voltage applied to the respective
pin. These states are defined as “0” (Low), “M” (Middle), and
“1” (One). Each of these states has a defined voltage range
that is interpreted by the SM560 as a “0,” “M,” or “1” logic state.
Refer to
Table 2
for voltage ranges for each logic state. By
using two equal value resistors (typically 20K) the “M” state
can be easily programmed. Pins 6 or 7 can be tied directly to
ground or VDD for Logic “0” or “1” respectively.
