    Hello,

    That's a read only status flag register (TRM pg 70). Use 0x002D, instead of 0x0057 to toggle CAL_EN. See TRM for more details.

    13.1.25 ManufacturerAccess() 0x002D CALIBRATION Mode

    This command disables/enables entry into CALIBRATION mode. Status is indicated by the ManufacturingStatus()[CAL_EN] flag. CALIBRATION mode is disabled upon a reset.
