F_EVENT
FIFO Event
• Indicates if either F_WMKF or F_OVF flags are set (logical OR).
• The F_STATUS register must be read to determine which event(s) occurred.
• The F_STATUS register must be read to determine which event(s) occurred.
0: FIFO Event not detected
1: FIFO Event was detected
4:0
FE_TIME
Number of ODR periods elapsed since F_EVENT was set
• indicates the number of samples acquired since a FIFO event flag (overflow or watermark) was
asserted.
6.7 0x0B: INT_SOURCE_FLAG
The INT_SOURCE_FLAG register provides the event-flag status for the functions
within the device. Reading the INT_SRC_FLAG register does not reset any event-flag
source bits; they are reset by reading the appropriate event source register. The content
of this register is reset upon a transition from Standby to Active or from Ready to
Active modes.
