CPLD MaxII, pull up resistor and led

Hello I have to drive 26 Leds through the CPLD MaxII. I have seen that this CPLD have internal pull up resistor that can be enable or not and apparently we can choose their value. My...

The maximum forward current is 50ma. I will use PWM to drive the LED.

I don't know what is multiplexing and how to do that in the CPLD, I am a begginer. I will check that (but if you want or have time to explain feel free :)).

The other proof that I am a begginer, is that I didn't know what was a common chip resistor (I've already check).

Thanks for your help
