Figure 16. Timing of Y shift registers (for row selection)
Figure 17. End-of-scan pulse
End-of-scan: EOS_YL, EOS_YR, EOS_X
All 3 shift registers are equipped with 'end-of-scan' pulses.
These pulses are low during the clock period after the last pixel
or row has been read out, also in viewfinder mode.
At the EOS_X pulse, the electrical dark reference level is put
on the readout bus. This voltage remains on the bus until the
SIN pulse goes high. During the row blanking time, this voltage
can be used for the offset adjustment of the output amplifier.
The SIN high forces the DCREF voltage on the output bus.
We advise not to use the EOS pulses as an input for the row
blanking time sequence generation, but to use simple
counters instead. If by some reasons the EOS signal is absent
or subject to glitches, the system would hang. EOS is intended
as diagnostic means.
Row initialization
During the row blanking time (which occurs at the beginning of
every row read), several tasks are executed: selection of a
new row, readout of this row by double sampling, reset of a
new row, and possibly (slow) offset adjustment of the output
amplifier. Therefore, a pulse patterns must be applied to
several signals during this time. There is some freedom to
make this pattern. The constraints are listed below:
