Drop Debounce
Drop event debounce value, the number
000: 1 drop event
of drop events detected must reach this
001: 2 adjacent drop events
count for the final event to be valid.
010: 3 adjacent drop events
… : 4 ≤ n ≤ 7 adjacent drop events
111: 8 adjacent drop events
Drop Interrupt
The DROPD bit in the TILT: Status
0: Disable drop event interrupt
Register will be set upon event
1: Enable drop event interrupt
occurrence regardless of this bit setting.
Drop Mode
0: Mode A: Drop detection is a summation of all 3 axes:
Drop is detected when:
Sum( mag(X) + mag(Y) + mag(Z) ) < 0.5g ± DROP_TH Threshold
else Drop not detected;
1: Mode B: Drop detection is the logical AND of three comparisons:
Drop is detected when:
mag(X) < 0.5g ± DROP_TH Threshold and
mag(Y) < 0.5g ± DROP_TH Threshold and
mag(Z) < 0.5g ± DROP_TH Threshold
else Drop not detected.
