The maximum output width cannot be greater than 4096
pixels wide (2048 if downsampling greater than 2 is used
with 7 filter taps)
This value must be EVEN and the number of bytes
written to SDRAM must be a multiple of 16-bytes if the
vertical resizing factor is greater than 1x (upsizing)

Description
INPUT CONFIGURATION REGISTER This register must be used when the input pixel data comes from
the PREVIEW module. must be set to 0 is the input pixel data comes from memory.

This field makes sense when the resizer obtains its input
from the preview engine/CCDC
When the resizer gets its input from SDRAM, this field
must be set to 0

HORZ_ST
Horizontal start pixel. Pixels are coded on 16 bits for YUV
RW
0x0000
and 8 bits for color separate data.
When the resizer gets its input from SDRAM, this field
must be set to <= 15 for YUV 16-bit data and <= 31 for
8-bit color separate data
Horizontal starting pixel value is in number of pixels if
input is from SDRAM.
If the input to the resizer is from CCDC/preview engine,
this field must be programmed as follows:
(1) Program this field using number of bytes (twice
number of pixels).
(2) Change the lowest bit to reflect start position in pixels
(effectively change from a value 0 to a value 1 if required)
