ITIPP (Transistor Q1) Current Measurement.
Reflects the current flowing into the ITIPP pin of the Si3200 (transistor Q1 of a discrete
circuit). 3.097 µ A/LSB, 2’s complement.
Loop Closure Detection Debounce Interval.
Programs the debounce interval during the loop closure detection process. Program-
mable range is 0 to 40.96 s, 1.25 ms/LSB.
Loop Closure Filter Coefficient.
Programs the digital low-pass filter block in the loop closure detection circuit.
Refer to "Loop Closure Detection" on page 32 for calculation.
