ADXRS453 - PLL & Q errors

After trying to receive data for the first time from the EVAL-ADXRS453Z-V breakout board of the ADXRS453, I've found out that the gyro data is invalid as the bits PLL and Q -which indicate a failure in the phase-locked loop functional circuit block and quadrature error, respectively- are constantly set. I followed the start-up procedure as described in the datasheet (0x20000003 followed by 0x20000000s with enough delay in between). Does this mean that the chip is faulty, and if not, how can I (or can I) fix this issue?
