Revision 8.4 - 24 Oct 2002 :
The
to control the sync and strobe signals.
The sr bit when enabled causes the SYNC signal to go
high for exactly one clock cycle, and then returns to a
low. It remains low until the sr bit is enabled again.
The sa bit when enabled causes the SYNC signal high
until this bit is disabled. This causes continuous frame
processing.
The se bit when enabled will allow for an external signal
to drive the SYNC signal via the SYNC pin on the chip.
The sae bit when enabled will enable the STROBE sig-
nal to be generated automatically by the sensor.This will
only work in SFRS (Single Frame Rolling Shutter). The
STROBE signal is goes high when all the Rows in the
Frame are integrating together.
The saw bit allows the user to select how long the
STROBE signal is going to be on. If the bit is set to 1
(Setting 1), causes the STROBE Signal to be on from
the time all the Rows are integrating to 1 Row time

Description
the bit is set to 0 (Setting 0), causes the STROBE signal
to on for a duration of 1 Row time (T
all Rows are integrating
The sso bit ,when enabled, forces the STROBE signal
and thereby the STROBE Pin high until it is reset back
to 0. When this bit is set high - the sae and saw bit set-
tings become negligible.
