INC4
Interrupt Control 4. This register controls routing of an interrupt reporting to physical interrupt pin INT1. Note that to
properly change the value of this register, the PC1 bit in CNTL1 register
must first be set to “0”.

FFI1
– Free fall interrupt reported on physical interrupt pin INT1
FFI1 = 0
– disable
FFI1 = 1
– enable
BFI1
– Buffer full interrupt reported on physical interrupt pin INT1
BFI = 0
– disable
BFI = 1
– enable
WMI1
– Watermark interrupt reported on physical interrupt pin INT1
WMI1 = 0
– disable
WMI1 = 1
– enable
Note: WMI & BFI1 are level triggered interrupt source. If the valid condition persists, and the
interrupt stays enabled, the interrupt will block any further interrupts from other sources from
triggering the INT1 pin. To let other interrupt sources through, WMI/BFI1 needs to be cleared
once detected.
DRDYI1
– Data ready interrupt reported on physical interrupt pin INT1
DRDYI1 = 0
– disable
DRDYI1 = 1
– enable
BTSI1
– Back to sleep interrupt reported on physical interrupt pin INT1
BTSI1 = 0

BTSI1 = 1

TDTI1
– Tap/Double Tap interrupt reported on physical interrupt pin INT1
TDTI1 = 0
– disable
TDTI1 = 1
– enable
WUFI1
– Wake-Up (motion detect) interrupt reported on physical interrupt pin INT1
WUFI1 = 0
– disable
WUFI1 = 1

TPI1
– Tilt position interrupt reported on physical interrupt pin INT1
TPI1 = 0
