1. The power down sequence is triggered by the I2C power down request, however the power down

sequence will only start after the end of the frame when all active data has been transferred to the output

interface. Once complete, the CSI-2 data signals enter LP11. The CSI-2 clock will enter LP11 with a delay

of 5 µs (corresponding to Tclk_post + Tclk_trail) after the data signals. The device will remain in LP11

unless the sensor restarts streaming or RESET_N is pulled low.
