SYNC_YR is not identical to SYNC_YL. SYNC_YR is used in
electronic shutter operation. The CLK_YR is driven identical to
CLK_YL, but the SYNC_YR pulse leads the SYNC_YL pulse by
a certain number of rows. This lead time is the effective
integration (electronic shutter ~) time. Relative to the row timing,
both SYNC pulses are given at the same time position, once for
each frame, but during different rows.
SYNC_YL is pulsed when the first row is read out and SYNC_YR
is pulsed for the electronic shutter to start for this first row. CAL
is pulsed on the first row too, 2 s later than SYNC_YL.

The minimal idle time is 1.4 s (before starting reading pixels).
However, do not read out pixels during the complete row initial-
ization process (in between the rising edge on S and the falling
edge on L/R). In this case, the total idle time is minimal. This
timing assumes that the Y start register was loaded in advance,
which can occur at any time but before the pulse on SYNC_YL
or SYNC_YR.
