The high even and low even spaces in
EPPI_CTL.DLEN 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.

High Even Clipping Threshold (Luma Data).
The EPPI_EVENCLIP.HIGHEVEN bit field selects the clipping threshold for luma
data. The high even spaces are 16-bits wide and (depending on the
EPPI_CTL.DLEN selection) only the corresponding video component bits are con-
sidered for clipping.
Low Even Clipping Threshold (Luma Data).
The EPPI_EVENCLIP.LOWEVEN bit field selects the clipping threshold for luma
data. The low even spaces are 16-bits wide and (depending on the EPPI_CTL.DLEN
selection) only the corresponding video component bits are considered for clipping.
