3.3.3

Standby state

Standby state preserves the contents of the register settings. I2C communications are

supported in this mode. The internal video timing is reset to the start of a video frame in

preparation for the enabling of active video. The previous settings of exposure and gain are

preserved. The system clock must remain active when communicating with the image

sensor.

If the MIPI CSI-2 interface is in use then the state of the bus in Standby depends on whether

the previous state was Reset or Streaming. If the previous state was Reset then all MIPI

CSI2 data lines remain at high impedance. If the previous state was Streaming then the

MIPI CSI2 data lines go to LP11 state while in Standby state.

Standby state is entered from reset by setting RESET_N high, or from streaming by writing

to the mode_select register; or by commanding a software reset by writing to the

software_reset register.

Note:

After a software reset or the transition of RESET_N to high, all registers are returned to their

default values.

3.3.4

Streaming state

Streaming state allows live video data to be streamed to the output. Streaming mode is

entered by writing to the mode_select register.
