INT_CTRL_REG2
This register controls motion detection axis enabling. Per Table 17, if an axis‟ bit is set to one (1), a
motion on that axis will generate an interrupt. If it is set to zero (0), a motion on that axis will not
generate an interrupt. Note that to properly change the value of this register, the PC1 bit in
CTRL_REG1 must first be set to “0”.

This register controls the tap detection direction axis enabling. Per Table 18, if a direction‟s bit is set
to one (1), a single or double tap in that direction will generate an interrupt. If it is set to zero (0), a
single or double tap in that direction will not generate an interrupt. Note that to properly change the
value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.
