Check Engine Light

I had this code pop up on my 2012 GMC Sierra with the 4.8L this morning.

I reset it on my way to work and it never came back on. I cannot find a definitive answer on what this code represent?

 Can anyone point me in the right direction?

Iso/sae code,can malfunction, should be good to go on reset,a hiccup in system

Internal pcm code,split second communication error,no problems felt,good to go,like a good sneeze, wasn't paying attention as fast as should,brain fart
