INT_CTRL_REG1
This register controls the settings for the physical interrupt pin (11). Note that to properly change the
value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.

IEN enables/disables the physical interrupt pin (11)
IEN = 0 – physical interrupt pin (11) is disabled
IEN = 1 – physical interrupt pin (11) is enabled
IEA sets the polarity of the physical interrupt pin (11)
IEA = 0 – polarity of the physical interrupt pin (11) is active low
IEA = 1 – polarity of the physical interrupt pin (11) is active high
IEL sets the response of the physical interrupt pin (11)
IEL = 0 – the physical interrupt pin (11) latches until it is cleared by reading INT_REL
IEL = 1 – the physical interrupt pin (11) will transmit one pulse with a period of
approximately 0.03 - 0.05ms
IEU sets an alternate unlatched response for the physical interrupt pin (11) when the motion
interrupt feature (WUF) only is enabled.
IEU = 0 – the physical interrupt pin (11) latches or pulses per the IEL bit until it is cleared
by reading INT_REL
IEU = 1 – the physical interrupt pin (11) will follow an unlatched response if the motion
interrupt feature is enabled
