Stream/Standby Control
The sensor supports a soft standby mode. In this mode, the external clock can be option-
ally disabled to further minimize power consumption. If this is done, then the “Power-
Up Sequence” on page 58 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
