For a PIC24HJ32GP202, what should the value of C, the decoupling capacitor connected to the pullup and current limiting resistors be? The manual doesn't specify a value. (section 2.4).
There never seems to be a standard for the cap rating unit, and I always used to get frustrated when I couldn't work out what nF, pF or uF were in other units!
I do it the lazy way now, my calculator has the units on it so I can just press a button to convert

I know they are all standard units, it's peoples personal preference as to which one they use, it just gets confusing when beginning electronics when people mention the different units.
I'm past that now, but I was just referring back to when I started out.
Good link AtomSoft, even better than a calc! lol
Mike is correct, there is no cap on MCLR, just a pull up resistor, the decoupling capacitor is between VDD and VSS.
But rarely do you need to, usually an R suffices. In fact a C can screw things up. If it's too large the pin may rise too slowly to properly latch a rising edge and the part may not start or respond to ICSP/ICD. On the other hand, the minimum is zero, so... go with zero unless you have a known reason to do otherwise.
