11.4

SLV1_ADD (05h)

C slave address of the second external sensor (Sensor2) register (r/w).

11.5

SLV1_SUBADD (06h)

Address of register on the second external sensor (Sensor2) register (r/w).

Table 215. SLAVE0_CONFIG register description

Slave0_rate[1:0]

Decimation of read operation on Sensor1 starting from the sensor hub trigger.

Default value: 00

(00: no decimation

01: update every 2 samples

10: update every 4 samples

11: update every 8 samples)

Aux_sens_on[1:0]

Number of external sensors to be read by sensor hub. Default value: 00

(00: one sensor

01: two sensors

10: three sensors

11: four sensors)

Src_mode

Source mode conditioned read(1). Default value: 0

(0: source mode read disabled; 1: source mode read enabled)

Slave0_numop[2:0]

Number of read operations on Sensor1.

1. Read conditioned by the content of the register at address specified in

DATAWRITE_SRC_MODE_SUB_SLV0 (0Eh) register. If the content is non-zero the operation continues

with the reading of the address specified in the SLV0_SUBADD (03h) register, else the operation is

interrupted.
