Rolling Shutter Operation
The integration of the light in the image sensor is done during
readout of the other lines.
The only difference with synchronous shutter is that the
TIME_OUT pin is used to indicate when the Y_SYNC pulse for
the right Y-shift-register (reset Y-shift register) is generated.
This loads the right Y-shift-register with the pointer loaded in
register YR_REG. The Y_SYNC pulse for the left Y-shift
register (read Y-shift register) is generated with Y_START.
The INT_TIME register defines how many lines have to be
counted before the Y_SYNC of the right Y-shift-register is
generated, hence defining the integration time. See also
“INT_TIME Register (11:0)” on page 14

Windowing in X-direction
An X_LOAD pulse overrides the internal X_SYNC signal,
loading a new X-pointer (stored in the X_REG register) into the
X-shift-register.
The X_LOAD pulse has to appear on the falling edge of
SYS_CLOCK and has to remain 2 SYS_CLOCK cycles high
overlapping 2 rising edges of SYS_CLOCK. On one of the 2
rising edges of SYS_CLOCK the new X-pointer is loaded.
T
from the previous register load to the rising edge of X_LOAD.
It depends on the settling time of the register and the
X-decoder.
The actual time to load the register itself depends on the
interface mode that is used.
The parallel interface is the fastest.
