The FID values for the current field or frame are reported in the Status Registers. When a new field or frame enters, the current FID values are saved into the previous FID status registers and the new FID value is loaded into the current FID register.
Following a reset, the previous and current FID status registers are set to ‘1.’ The first two fields or frames are ignored. On the third input field or frame after a reset, the previous FID is loaded with the current FID (‘1’), and the current FID is loaded with the actual FID. By the fourth field or frame after a reset, both the previous and current FID values should represent the values found in the input stream.
The FID values are reported for each camera source in both Pixel Input Clock Domains.
