Latency When Changing Integration
1. During frame n, the new integration time is held in the R0x0B live register.
2. At the start of frame (n + 1), the new integration time is transferred to the exposure
3. When frame (n + 1) is read out, it is integrated using the new integration time. If the
With automatic exposure control disabled (R0xAF, bit 0 is cleared to LOW), and if the
total integration time (R0x0B) is changed via the two-wire serial interface while
FRAME_VALID is asserted for frame n, the first frame output using the new integration
time is frame (n + 2). Similarly, when automatic exposure control is enabled, any change
to the integration time for frame n first appears in frame (n + 2) output.
The sequence is as follows:

control module. Integration for each row of frame (n + 1) has been completed using
the old integration time. The earliest time that a row can start integrating using the
new integration time is immediately after that row has been read for frame (n + 1).
The actual time that rows start integrating using the new integration time is depen-
dent on the new value of the integration time.
integration time is changed (R0x0B written) on successive frames, each value written
is applied to a single frame; the latency between writing a value and it affecting the
frame readout remains at two frames.
However, when automatic exposure control is disabled, if the integration time is
changed through the two-wire serial interface after the falling edge of FRAME_VALID
for frame n, the first frame output using the new integration time becomes frame
(n + 3).
