MPU6050 burst read and user-facing registers

Hi
Hi, I use DMA (i2c) to read all 14 register starting from ACCEL_XOUT_H in burst mode described on page 37 of PS. Every received byte is followed by ACK, the last byte by NACK according to "Burst read sequence" picture on page 37. Everything seems to be ok, but I wonder if i should do something more to enable reading data from user-facing registers describing i RM on page 30. The RM says that data reading can be done from user-facing registers or from "ordinary" registers and user should take care about data constancy. How to tell MPU6050 to use user-facing registers? If the i2c burst read sequence is enough, how the 6050 knows if first byte should be send from user-facing or "ordinary" register?

Thank you in advance
