23.0 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 takes up to 16

input signals, and through the use of configurable

gates, reduces the 16 inputs to four logic lines that drive

one of eight selectable single-output logic functions.

Input sources are a combination of the following:

• I/O pins

• Internal clocks

• Peripherals

• Register bits

The output can be directed internally to peripherals and

to an output pin.

Refer to Figure 23-1 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
