BOOTEND

Boot sequence complete event flag

• Asserted as soon as the device boot sequence has completed.

1: Boot sequence is complete

0: Boot sequence is not complete

2

SRC_FIFO

FIFO event source flag

• Indicates that the FIFO triggered the interrupt
• Cleared by reading the register

1: F_OVF or F_WMKF are set, provided the FIFO interrupt is enabled (

CTRL_REG2[INT_EN_FIFO=1])

0: Cleared by reading the register

1

SRC_RT

Rate threshold event source flag

• Indicates that the rate threshold event flag triggered the interrupt
• Cleared by reading RT_SRC register

0

SRC_DRDY

Data ready event source flag

• Asserted whenever a data-ready event triggers the interrupt
• Cleared whenever the MSB's of the X, Y, and Z axes sample data are read
• Cleared by reading the MSB's of the X, Y, and Z axes sample data

The WHO_AM_I register contains the device identifier which is factory programmed to
0xD1.

CTRL_REG0 is used for general control and configuration of the device. The bit fields
in CTRL_REG0 should be changed only in Standby or Ready modes. Accuracy of the
output data is not guaranteed if these bits are changed when the device is in Active
mode.
