When the slave address matches the I2C device ID with read control bit, data are immediately transferred after ack command. Reading data transmission begins from core register 0 to final register until “P”(STOP) occurs. The data is transmitted from LSB to MSB, and the data of register 0 (0x96) is fixed as reference check point for read mode.
