_BIT_SET

0(1)

1. This bit must be set to 0 for the correct operation of the device.

Table 194. EMB_FUNC_SRC register description

PEDO_RST_STEP

Reset pedometer step counter. Read/write bit.

(0: disabled; 1: enabled)

STEP_DETECTED

Step detector event detection status. Read-only bit.

(0: step detection event not detected; 1: step detection event detected)

STEP_COUNT_DELTA_IA

Pedometer step recognition on delta time status. Read-only bit.

(0: no step recognized during delta time;

1: at least one step recognized during delta time)

STEP_OVERFLOW

Step counter overflow status. Read-only bit.

(0: step counter value < 216; 1: step counter value reached 216)

STEPCOUNTER_BIT_SET

This bit is equal to 1 when the step count is increased. If a timer period is programmed in

PEDO_SC_DELTAT_L (AAh) and PEDO_SC_DELTAT_H (ABh) embedded advanced features

(page 1) registers, this bit is kept to 0.

Read-only bit.
