Free-Fall and Wake-Up Registers
AN2335
28/40
8.6
FF_WU_CFG_2 (34h)
Free-fall and wake-up configuration register for interrupt source 2.
Two structures can be used to generate interrupts. They have exactly the same
configuration capability and they are completely independent.
The interrupt result of each structure can be sent indifferently to INT1 or INT2 pin using
CTRL_Reg3 register.
AOI
LIR
ZHIE
ZLIE
YHIE
YLIE
XHIE
XLIE
AOI
And/Or combination of Interrupt events. Default value: 0
(0: OR combination of interrupt events; 1: AND combination of interrupt events)
LIR
Latch Interrupt request into FF_WU_SRC reg with the FF_WU_SRC reg cleared by
reading FF_WU_SRC_1 reg. Default value: 0
(0: interrupt request not latched; 1: interrupt request latched)
ZHIE
Enable interrupt generation on Z high event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value higher than preset threshold)
ZLIE
Enable interrupt generation on Z low event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value lower than preset threshold)
YHIE
Enable interrupt generation on Y high event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value higher than preset threshold)
YLIE
Enable interrupt generation on Y low event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value lower than preset threshold)
XHIE
Enable interrupt generation on X high event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value higher than preset threshold)
XLIE
Enable interrupt generation on X low event. Default value: 0
(0: disable interrupt request;
1: enable interrupt request on measured accel. value lower than preset threshold)
