Will any code reader read pending codes?

[v8440]

Hi all,
I have a cheap code reader, but I don't know whether it would tell me if there's a pending code set. My truck has kind of stuttered once or twice when taking off gently from a stop, but the check engine light has not come on and the code reader says no dtc's found. Can I be confident that I would know about pending codes if there were some, or do some readers not show pending code?

My older scan gauge (circa 2010) was not able to read a CEL code recently. It defaulted to P0000 and the SA since let me know it had stored misfire codes. YMMV.
