Height of the clipping area
The height of the clipping area can vary between 0 (HEIGHT_CLIP =
‘0_d’) and 1023 pixels (HEIGHT_CLIP = ‘1023_d’).
Clipping Offset (Bit 10 … 4)
The LSBs of C_OFFSET are defined by instruction CUR.
Width of the clipping area
The width of the clipping area can vary between 0 (WIDTH_CLIP = ‘0_d’)
and 2046 pixels (WIDTH_CLIP = ‘2046_d’).
