Preliminary Datasheet

8.4 (0x02 â 0x07) XOUT, YOUT & ZOUT Data Output Registers

The measurements from sensors for the 3-axes are available in these 3 registers. The most-

significant bit of the value is the sign bit, and is sign extended to the higher bits.

Software must set only one of these two bits to â1â, depending upon if the I2C or SPI

interface will be used for external communications. No data will appear in XOUT, YOUT

and ZOUT registers if both the I2C_MODE_EN bit and SPI_MODE_EN bit are set to 0

(default).

When the FIFO is enabled, the output of the FIFO is mapped to registers 0x02 to 0x07, and

the data has a maximum resolution of 12-bits.

During FIFO reads, software must start a read at address 0x02 and complete a read to

address 0x07 for the FIFO pointers to increment correctly.

Once an I2C start bit has been recognized by the device, registers will not be updated until an

I2C stop bit has occurred. Therefore, if software desires to read the low and high byte registers

âatomicallyâ, knowing that the values have not been changed, it should do so by issuing a start

bit, reading one register, then reading the other register then issuing a stop bit. Note that all 6

registers may be read in one burst with the same effect.
