Note: The acceleration data is presented in 2's complement format. At 0 g acceleration the output is ideally 0000h.
Note: INT_STATUS: The bits in this interrupt status register and corresponding SPI frame bits are cleared after register has
been read. Register reading is treated as interrupt acknowledgement signal. These bits are kept active even failure
condition is over if they are not acknowledged.

Description
ASIC revision identification number, each ASIC version has
different REVID-number.
Please refer to chapter 4.5.2 for CONTROL register details.
Reserved
Analog test mode status
1 – Test mode is active
0 – Test mode is not active
EEPROM Checksum Error. ST bit of SPI frame is also set if
CSMERR is set.
SPI frame error. Bit is reset, when next correct SPI frame is
received. Bit is also visible in SPI frame.
Writing 0C'hex, 05'hex, 0F'hex in this order resets component.
X-axis LSB data frame (Read always X_MSB prior to X_LSB)
Reserved
X-axis MSB data bits (Reading of this register latches X_LSB)
Reserved
Y-axis LSB data frame (Read always Y_MSB prior to Y_LSB)
Reserved
Y-axis MSB data bits (Reading of this register latches Y_LSB)
Reserved
Z-axis LSB data frame (Read Z_MSB prior to Z_LSB)
Reserved
Z-axis MSB data bits (Reading of this register latches Z_LSB)
Reserved
Data bits [7:0] of temperature sensor.
Read always TEMP_MSB prior to TEMP_LSB.
Data bits [15:8] of temperature sensor.
Reading of this register latches TEMP_LSB.
Reserved
Saturation status of output data
1 – Over range detected, one or 2-3 of xyz axis is saturated and
output data is not valid.
0 – Data in range
SAT bit is also visible in SPI frame. This bit can be active after
start-up or reset stage before signal path settles to final value and
it has to be acknowledged in start-up sequence (see Table 8) or
after SW reset or after PORST stage.
Status of gravitation based start-up self test
1 – Failure
0 – No failure
STS sets also ST bit in SPI frame.
Status of continuous self test
1 – Failure
0 – No failure
STC sets also ST bit in SPI frame.
