PIC CLC Demo and Configuration
In this little demo project, I used a CLC - Configurable Logic Cell - on a PIC MCU to make a system wake up from sleep only when the three input switches are pressed simultaneously.
The CLC can combine signals from different sources and run simple logic operations on them without occupying the processor or other resources. This can save power, code lines etc. and sometimes allow things that simply couldn't be done otherwise with an 8-bit MCU like this.
For nitpickers: Yes, the code I showed could use some clean-up :-)
