IEN enables/disables the physical interrupt pin
IEN = 0 – physical interrupt pin is disabled
IEN = 1 – physical interrupt pin is enabled
IEA sets the polarity of the physical interrupt pin
IEA = 0 – polarity of the physical interrupt pin is active low
IEA = 1 – polarity of the physical interrupt pin is active high
IEL sets the response of the physical interrupt pin
IEL = 0 – the physical interrupt pin latches until it is cleared by reading INT_REL
IEL = 1 – the physical interrupt pin will transmit one pulse with a period of 50 us
STPOL sets the polarity of Self-Test
STPOL = 0 – Negative
STPOL = 1 – Positive
SPI3E sets the 3-wire SPI interface
SPI3E = 0 – disabled
SPI3E = 1 – enabled
INC2
This register controls which axis and direction of detected motion can cause an interrupt. Note that to
properly change the value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.
