when the pixel counter reaches the value loaded in the
NROF_PIXELS register (after a complete row read out).
T
value loaded in the NROF_LINES register and stays high for one
line period (until the next falling edge of Y-CLOCK).
On Y_START the left Y-shift-register of the image core is loaded
with the YL-pointer that is loaded in to register YL_REG.
Pixel Output
The pixel signal at the PXL_OUT1 output becomes valid after
five SYS_CLOCK cycles when the internal X_SYNC (= start of
PIXEL_VALID output or external X_LOAD pulse) pulse is
asserted. (See

Advanced Operation:
It was observed during characterization of the IBIS5-B-1300
image sensor that there are column non-uniformities in the
image in syncronous shutter mode, when the Y-readout pointer
is still selecting a line during the global reset for the next frame.
To avoid this problem, an advanced timing has been generated
for the syncronous shutter mode. Please look into application
note - FAQ for IBIS5-1300 image sensor (AN6004 - question 12)
for more information. The application note discusses the cause
and corrective action for this problem.
