$06: Interrupt Setup Register

INTSU

FBINT

0: Front/Back position change does not cause an interrupt

1: Front/Back position change causes an interrupt

PLINT

0: Up/Down/Right/Left position change does not cause an

interrupt

1: Up/Down/Right/Left position change causes an interrupt

PDINT

0: Successful tap detection does not cause an interrupt

1: Successful tap detection causes an interrupt

ASINT

0: Exiting Auto-Sleep does not cause an interrupt

1: Exiting Auto-Sleep causes an interrupt

GINT

0: There is not an automatic interrupt after every

measurement

1: There is an automatic interrupt after every measurement,

when g-cell readings are updated in XOUT, YOUT, ZOUT

registers, regardless of whether the readings have changed

or not. This interrupt does not affect the Auto-Sleep or Auto-

Wake functions.

SHINTX

0: Shake on the X-axis does not cause an interrupt or set the

Shake bit in the TILT register

1: Shake detected on the X-axis causes an interrupt, and sets

the Shake bit in the TILT register

SHINTY

0: Shake on the Y-axis does not cause an interrupt or set the

Shake bit in the TILT register

1: Shake detected on the Y-axis causes an interrupt, and sets

the Shake bit in the TILT register

SHINTZ

0: Shake on the Z-axis does not cause an interrupt or set the

Shake bit in the TILT register

1: Shake detected on the Z-axis causes an interrupt, and sets

the Shake bit in the TILT register.

The active interrupt condition (IRQ = 0 if IAH = 0, IRQ = 1 if IAH = 1) is released during the acknowledge bit of the slave address
