By default, Output Port 0 is assigned to transmit an integration enabled 
(Int-En) signal that indicates when exposure is taking place. By default, 
Output Port 1 is assigned to transmit a trigger ready (Trig-Rdy) signal that 
goes high to indicate the earliest point at which exposure start for the next 
frame can be triggered. Please refer “1.6 Integrate Enabled Signal Timing” 
for a detailed camera signal integrate timing chart. The pin assignment of 
the camera output sig
 can be changed. Please
