INC5
This register controls the settings for the physical interrupt pin INT2. Note that to properly change the
value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.

IEN2 enables/disables the physical interrupt pin
IEN2 = 0 – physical interrupt pin is disabled
IEN2 = 1 – physical interrupt pin is enabled
IEA2 sets the polarity of the physical interrupt pin
IEA2 = 0 – polarity of the physical interrupt pin is active low
IEA2 = 1 – polarity of the physical interrupt pin is active high
IEL2 sets the response of the physical interrupt pin
IEL2 = 0 – the physical interrupt pin latches until it is cleared by reading INT_REL
IEL2 = 1 – the physical interrupt pin will transmit one pulse with a period of 50 us
INC6
This register controls routing of interrupt reporting to physical interrupt pin INT2. Note that to properly
change the value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.
