Description
Colour code outputs. These outputs indicate from which channel the
current output sample was taken (R = 00X, G = 01X, B = 10X).
Two codes are provided per channel.
Out-of-range signal, active high. This signal indicates that the current
output pixel has exceeded the maximum or minimum achievable
somewhere within the pixel processing.
Output tri-state control, all outputs enabled when OEB=0
Data valid output, active low.
Reset input, active low. This signal forces a reset of all internal registers.
Control interface parallel (high) or serial (low, default)
Serial Interface: serial interface input data signal
Parallel interface: high = data, low = address

Digital IP
Serial Interface: serial interface clock signal
Parallel interface: high = OP[11:4] is output, low = OP[11:4] is input bus
