Preliminary specification
Digital video scaler
SAA7186
14 PROGRAMMING EXAMPLE
Slave address byte is B8h at pin IICSA = 0 (or BCh at pin IICSA = +5 V).
This example shows the setting via I
2
C-bus for the processing of a picture segment at 1:1 horizontal and vertical scale.
Values in brackets [..]:
If no scaling or panning is wanted,
the parameters XD, XS, YD and YS should be set to the maximum value 3FFh.
the parameters XO and YO should be set to the minimum value 000h.
(in this case, HREF and VS from external define the SAA7186 processing window).
