CHANGING SENSOR MODES

All register writes are delayed by one frame. A register

that is written to during the readout of frame n will not be

updated to the new value until the readout of frame n + 2.

This includes writes to the sensor gain and integration

registers.

Real−Time Context Switching

In the AR0141CS, the user may switch between two full

bit in R0x30B0[13]. When the context switch is configured

to context A the sensor will reference the context A registers.

If the context switch is changed from A to B during the

readout of frame n, the sensor will then reference the context

B coarse_integration_time registers in frame n + 1 and all

other context B registers at the beginning of reading frame

n + 2. The sensor will show the same behavior when

changing from context B to context A.
