Question
ADXL313 datasheet Rev A claims the default value for PARTID register is 0xDC
and that it matches octal 313. Octal 313 is 0xCB, and that's what the device is
returning.
Answer
This is a typo error. This will be corrected at the next revision of this
datasheet.
You are of course correct, the device ID should be 0xCB or 313 Octal and not
0xDC like in REV A datasheet.
