VDD_VIN

Write enable input signal is used by external device (AFE/TG) to gate the DDR

CAM_WE

output of the CCDC module. Alternately, the field identification input signal is

N_FIELD /

I/O/Z

used by external device (AFE/TG) to indicate the which of two frames is input to

VDD_VIN

GIO083

the CCDC module for sensors with interlaced output. CCDC handles 1- or 2-field

sensors in hardware. GIO: GIO[083]

Vertical synchronization signal that can be either an input (slave mode) or an

CAM_VD /

I/O/Z

output (master mode). Tells the CCDC when a new frame starts.

GIO084

VDD_VIN

GIO: GIO[084]

Horizontal synchronization signal that can be either an input (slave mode) or an

CAM_HD /

I/O/Z

output (master mode). Tells the CCDC when a new line starts.
