The Apollo3 datasheet linked to from the product page for the MicroMod Artemis board is a few revisions out of date at this point. This was a problem when I was looking up some constants for the CLKGEN module and found that the values didn’t match those I was reading from the board itself. The current revision (1.2.0) from Ambiq’s site seems to match with the board.
Thanks for the heads-up! We’ll get our docs updated
