Clipping Register for ODD (Chroma) Data Register

video components.
The high odd and low odd spaces in
bit selection) only the corresponding video component bits are considered for clipping.
For example, if the EPPI is programmed in 10-bit mode, bits [9:0] and bits [25:16] constitute the clipping thresh-
olds. The higher bits are (in this case) ignored.
Using the this method, 8-, 10-, 12- and 16-bit clipping thresholds can be set.
Note that when the EPPI is programmed in 16-, 20-, or 24-bit mode with the EPPI_CTL.SPLTWRD bit set, the
luma data gets the clipping threshold levels of the
ping threshold levels of the
Also, note that the
EPPI_EVENCLIP
EPPI_CTL.RGBFMTEN bit is set.
