TDTE enables the Directional Tap^TM function that will detect single and double tap events.
Note that to change the value of this bit, the PC1 bit must first be set to “0”.
TDTE = 0 – disable
TDTE = 1- enable
WUFE enables the Wake Up (motion detect) function that will detect a general motion event.
Note that to change the value of this bit, the PC1 bit must first be set to “0”.
WUFE = 0 – disable
WUFE = 1- enable
TPE enables the Tilt Position function that will detect changes in device orientation. Note that
to change the value of this bit, the PC1 bit must first be set to “0”.
TPE = 0 – disable
TPE = 1- enable
CTRL_REG2
Read/write control register that primarily controls tilt position state enabling. Per Table 13, if a state‟s
bit is set to one (1), a transition into the corresponding orientation state will generate an interrupt. If it is
set to zero (0), a transition into the corresponding orientation state 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”.
