Table 29. FIFO_CTRL2 register description
Enable pedometer step counter and timestamp as 4^th FIFO data set. Default: 0
(0: disable step counter and timestamp data as 4^th FIFO data set;
1: enable step counter and timestamp data as 4^th FIFO data set)
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.)
FIFO_TEMP_EN
FTH_[10:8]
Enable the temperature data storage in FIFO. Default: 0.
(0: temperature not included in FIFO; 1: temperature included in FIFO)
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
1. This bit is effective if the DATA_VALID_SEL_FIFO bit of the MASTER_CONFIG (1Ah) register is set to 0.
2. For a complete watermark threshold configuration, consider FTH_[7:0] in FIFO_CTRL1 (06h).
