The Configurable Logic Cell (CLC) provides programmable 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 into 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.

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
