SPIXopt
In the default case below,(Figure 15), SPIXopt=0, the
internal sample video switches turn ON a programmed
delay after the SBLK pulse ends, and turn OFF at the
end of the SPIX pulse. The turn ON delay is pro-
grammed by DelayB[8:6].
When SPIXopt = 1, the internal SPIX switches are
controlled only by the SPIX pulse. This mode is
intended for camera systems where the designer has
the ability to externally fine tune both the rising and
falling edges of SPIX to achieve optimum performance
(see Figure 16).
