Register description
TIMER_PEDO
_FIFO_EN
Table 22. FIFO_CTRL2 register description
Enable pedometer step counter and time stamp. Default: 0
(0: disable step counter and time stamp data;
1: enable step counter and time stamp data.)
TIMER_PEDO
_FIFO_DRDY
FTH_[11:8]
FIFO write mode. 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 threshold level setting⁽¹⁾. 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. For a complete watermark threshold configuration, consider FTH_[11:8] in FIFO_CTRL1 (06h)
9.4
FIFO_CTRL3 (08h)
FIFO control register (r/w).
