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.

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.
