Sensor synchronization resolution ratio (r/w)

Table 26. SENSOR_SYNC_RES_RATIO register description

10.4

FIFO_CTRL1 (06h)

FIFO control register (r/w).

Table 28. FIFO_CTRL1 register description

10.5

FIFO_CTRL2 (07h)

FIFO control register (r/w).

Table 30. FIFO_CTRL2 register description

Table 25. SENSOR_SYNC_RES_RATIO register

0(1)

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

0(1)

RR_1

RR_0

RR_[1:0]

Resolution ratio of error code for sensor synchronization:

00: SensorSync, Res_Ratio = 2-11

01: SensorSync, Res_Ratio = 2-12

10: SensorSync, Res_Ratio = 2-13

11: SensorSync, Res_Ratio = 2-14

FTH_7

FTH_6

FTH_5

FTH_4

FTH_3

FTH_2

FTH_1

FTH_0

FTH_[7:0]

FIFO threshold level setting(1). Default value: 0000 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 1 LSB = 2 bytes (1 word) in FIFO

1. For a complete watermark threshold configuration, consider FTH_[10:8] in FIFO_CTRL2 (07h).

Table 29. FIFO_CTRL2 register

0(1)

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

0(1)

FIFO_

TEMP_EN

FTH10

FTH_9

FTH_8

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(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_[7:0] in FIFO_CTRL1 (06h)
