CONFIGURABLE LOGIC CELL

(CLC)

The Configurable Logic Cell (CLCx) provides program-

mable logic that operates outside the speed limitations

of software execution. The logic cell selects any combi-

nation of the eight input signals and through the use of

configurable gates reduces the selected inputs to four

logic lines that drive one of eight selectable single-out-

put logic functions.

Input sources are a combination of the following:

• Two I/O pins

• Internal clocks

• Peripherals

• Register bits

The output can be directed internally to peripherals and

to an output pin.

Refer to Figure 19-1 for a simplified diagram showing

signal flow through the CLCx.

Possible configurations include:

• Combinatorial Logic

-AND

-NAND

- AND-OR

- AND-OR-INVERT

-OR-XOR

-OR-XNOR

• Latches

-S-R

- Clocked D with Set and Reset

- Transparent D with Set and Reset

- Clocked J-K with Reset
