Embedded functions registers description

11.3
PEDO_DEB_REG (14h)
The procedure to modify the pedometer debounce time is the following:
Write reg FUNC_CFG_ACCESS (01h) = 80h (Enables access to the embedded
functions)
Set debounce time in bits [3:7] of reg 14h (1LSB = 80 ms.This value must be > 0)
Write reg FUNC_CFG_ACCESS (01h) = 00h (Disables access to the embedded
functions registers)
Note:
All modifications of the content of the embedded functions registers have to be performed
with the device in power-down mode.
11.4
STEP_COUNT_DELTA (15h)
Time period register for step detection on delta time (r/w).

Table 157. PEDO_DEB_REG register description
DEB_ TIME[4:0]
If this time between steps is greater than DEB_TIME*80ms, the debouncer is
reactivated
DEB_ STEP[2:0] Minimum number of steps to increment step counter (debouncer)

SC_DELTA[7:0]
Time period value(1) (1LSB = 1.6384 s)
1. This value is effective if the TIMER_EN bit of the TAP_CFG register is set to 1 and the TIMER_HR bit of
the WAKE_UP_DUR register is set to 0.
