Stream/Standby Control

The sensor supports a soft standby mode. In this mode, the

external clock can be optionally disabled to further

minimize power consumption. If this is done, then the

“Power−Up Sequence” must be followed.

Soft Standby

Soft Standby is a low−power state that is controlled

through register R0x301A[2]. Depending on the value of

R0x301A[4], the sensor will go to Standby after completion

of the current frame readout. When the sensor comes back

from Soft Standby, previously written register settings are

still maintained. Soft Standby will not occur if the Trigger

pin is held high.

A specific sequence needs to be followed to enter and exit

from Soft Standby.

Entering Soft Standby:

1. Set R0x301A[12] = 1 if serial mode was used

2. Set R0x301A[2] = 0 and drive Trigger pin low

3. Turn off external clock to further minimize power

consumption

Exiting Soft Standby:

1. Enable external clock if it was turned off

2. Set R0x301A[2] = 1 or drive Trigger pin high

3. Set R0x301A[12] = 0 if serial mode is used
