Photography Framing Definition

What does "pcs" stand for in these photography specifications? 16M(L) 8fps/8pcs ,8M(M)11fps/16pcs,4M(S)11fps/3?
I recently got a professional digital camera, and in the specifications it says that it can capture continuous frames at a high speed 16M(L) 8fps/8pcs ,8M(M)11fps/16pcs,4M(S)11fps/32pcs. I've been trying to figure out what pcs means, but can't find a good definition.
Pictures.
8 frames per second, 8 pictures
11 frames per second, 16 pictures
etc.
It tells you how fast the shutter will click, and how many pictures it will take at that setting.
