IEN enables/disables the physical interrupt pin (7)
IEN = 0 – physical interrupt pin (7) is disabled
IEN = 1 – physical interrupt pin (7) is enabled
IEA sets the polarity of the physical interrupt pin (7)
IEA = 0 – polarity of the physical interrupt pin (7) is active low
IEA = 1 – polarity of the physical interrupt pin (7) is active high
IEL sets the response of the physical interrupt pin (7)
IEL = 0 – the physical interrupt pin (7) latches until it is cleared by reading INT_REL
IEL = 1 – the physical interrupt pin (7) will transmit one pulse with a period of 0.03 -
0.05ms
INT_CTRL_REG2
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”.
