Figure 1-1 • 40MX Logic Module
The 42MX devices contain three types of logic modules: combinatorial (C-modules), sequential (S-
modules) and decode (D-modules). Figure 1-2 illustrates the combinatorial logic module. The S-module,
shown in Figure 1-3, implements the same combinatorial logic function as the C-module while adding a
sequential element. The sequential element can be configured as either a D-flip-flop or a transparent
latch. The S-module register can be bypassed so that it implements purely combinatorial logic.
