STOP_ON

_WTM

COMPR_

RT_EN

0(1)

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

_RATE_0

WTM8

STOP_ON_

WTM

Sensing chain FIFO stop values memorization at threshold level

(0: FIFO depth is not limited (default);

1: FIFO depth is limited to threshold level, defined in FIFO_CTRL1 (07h) and

FIFO_CTRL2 (08h))

FIFO_COMPR_

RT_EN(1)

1. This bit is effective if the FIFO_COMPR_EN bit of EMB_FUNC_EN_B (05h) is set to 1.

Enables/Disables compression algorithm runtime

ODRCHG_EN

Enables ODR CHANGE virtual sensor to be batched in FIFO

UNCOPTR_

RATE_[1:0]

This field configures the compression algorithm to write non-compressed data at

each rate.

(0: Non-compressed data writing is not forced;

1: Non-compressed data every 8 batch data rate;

2: Non-compressed data every 16 batch data rate;

3: Non-compressed data every 32 batch data rate)

WTM8

FIFO watermark threshold, in conjunction with WTM_FIFO[7:0] in FIFO_CTRL1

(07h)

1 LSB = 1 sensor (6 bytes) + TAG (1 byte) written in FIFO

Watermark flag rises when the number of bytes written in the FIFO is greater

than or equal to the threshold level.
