i am using 20 bit component input(625i).in the hardware document its given with prime_mode reg= 0x00 and vid_std reg=0x0d cp processor is enabled,but in table 13 with prime_mode 0x00 ,the processor used is sdp. How can i make sure that cp circuit is activated.is der a flag or any particular value which indicates which processor is being used .the status register 2(0x12) always reads cp_free_run=1 irrespective of the input being connected or not.in hardware doc its given that the bit 7 and 6 are valid for hd,gr and pr.For sd mode are these bits not valid?
