1 LSB = 1/ODR. TLA7 through TLA0 define the time interval that starts after the first click

detection where the click detection procedure is disabled, in cases where the device is

configured for double click detection.

TIME WINDOW_A (3Dh)

1 LSB = 1/ODR. TW7 through TW0 define the maximum interval of time that can elapse

after the end of the latency interval in which the click detection procedure can start, in cases

where the device is configured for double click detection.
