NOTE: If XDA = YDA = ZDA = 0, samples per second is 120 samples/second, and Auto-Wake/Sleep feature is enabled,
XDA
1: X-axis is disabled for tap detection
0: X-axis is enabled for tap detection
YDA
1: Y-axis is disabled for tap detection
0: Y-axis is enabled for tap detection

the tap interrupt will reset the sleep counter.
The tap detection debounce filtering requires 2 adjacent tap detection tests to be the same to trigger a tap event and set the
Tap bit in the TILT (0x03) register, and optionally set an interrupt if PDINT is set in the INTSU (0x06) register. Tap detection
response time is nominally 0.52 ms.
Tap detection debounce filtering requires 3 adjacent tap detection tests to be the same to trigger a tap event and set the Tap
bit in the TILT (0x03) register, and optionally set an interrupt if PDINT is set in the INTSU (0x06) register. Tap detection
response time is nominally 0.78 ms.
Tap detection debounce filtering requires 4 adjacent tap detection tests to be the same to trigger a tap event and set the Tap
bit in the TILT (0x03) register, and optionally set an interrupt if PDINT is set in the INTSU (0x06) register. Tap detection
response time is nominally 1.04 ms.

Tap detection debounce filtering requires 254 adjacent tap detection tests to be the same to trigger a tap event and set the
Tap bit in the TILT (0x03) register, and optionally set an interrupt if PDINT is set in the INTSU (0x06) register. Tap detection
response time is nominally 66.04 ms.
Tap detection debounce filtering requires 255 adjacent tap detection tests to be the same to trigger a tap event and set the
Tap bit in the TILT (0x03) register, and optionally set an interrupt if PDINT is set in the INTSU (0x06) register. Tap detection
response time is nominally 66.3 ms.
Tap detection debounce filtering requires 256 adjacent tap detection tests to be the same to trigger a tap event and set the
Tap bit in the TILT (0x03) register, and optionally set an interrupt if PDINT is set in the INTSU (0x06) register. Tap detection
response time is nominally 66.56 ms.
