*Question* What is "Oversampling"?

[udellc]

I see in the Loom3 Serial monitor printout some standard output for SmartRock, but I see something strange I'd like explained. Here is original printout with the unexplained output broken out below: Initialized Serial!

==================

What is this? Oversampling setting: 512 C0 = 136 C1 = 37792 C2 = 34813 C3 = 24229 C4 = 23504 C5 = 35067 C6 = 28338 C7 = 58688 p_crc: 64 n_crc: 0

This is from the MS5803 standard library MS5803_02.cpp code. Function to check the CRC value
