WAKEUP_TIMER
This register sets the time motion must be present before a wake-up interrupt is set. Every count is
calculated as 1/OWUF delay period. Note that to properly change the value of this register, the PC1 bit
in CTRL_REG1 must first be set to “0”. Valid Entries are 1 to 255, zero is excluded.

SELF_TEST
When 0xCA is written to this register, the MEMS self-test function is enabled. Electrostatic-actuation of
the accelerometer, results in a DC shift of the X, Y and Z axis outputs. Writing 0x00 to this register will
return the accelerometer to normal operation.

WAKEUP_THRESHOLD
This register sets the threshold for wake-up (motion detect) interrupt is set. The KXCJK will ship from
the factory with this value set to correspond to a change in acceleration of 0.5g. Note that to properly
change the value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.
