FIFO_CTRL2 (07h)

FIFO control register (r/w).

Table 29. FIFO_CTRL2 register description

Table 28. FIFO_CTRL2 register

TIMER_PEDO

_FIFO_EN

TIMER_PEDO

_FIFO_DRDY

0(1)

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

0(1)

FIFO_

TEMP_EN

FTH10

FTH_9

FTH_8

TIMER_PEDO

_FIFO_EN

Enable pedometer step counter and timestamp as 4th FIFO data set. Default: 0

(0: disable step counter and timestamp data as 4th FIFO data set;

1: enable step counter and timestamp data as 4th FIFO data set)

TIMER_PEDO

_FIFO_DRDY

FIFO write mode(1). Default: 0

(0: enable write in FIFO based on XL/Gyro data-ready;

1: enable write in FIFO at every step detected by step counter.)

1. This bit is effective if the DATA_VALID_SEL_FIFO bit of the MASTER_CONFIG (1Ah) register is set to 0.

FIFO_TEMP_EN

Enable the temperature data storage in FIFO. Default: 0.

(0: temperature not included in FIFO; 1: temperature included in FIFO)

FTH_[10:8]

FIFO threshold level setting(2). Default value: 0000

Watermark flag rises when the number of bytes written to FIFO after the next

write is greater than or equal to the threshold level.

Minimum resolution for the FIFO is 1LSB = 2 bytes (1 word) in FIFO

2. For a complete watermark threshold configuration, consider FTH_[7:0] in FIFO_CTRL1 (06h).
