This register sets the video capture enlargement/reduction ratio.
Bit 31 to 27
VSCI (Vertical SCale Integer)
Sets integer part of vertical enlargement/reduction ratio
Bit 26 to 16
VSCF (Vertical Scale Fraction)
Sets fraction part of vertical enlargement/reduction ratio
Bit 15 to 11
HSCI (Horizontal SCale Integer)
Sets integer part of horizontal enlargement/reduction ratio
Bit 10 to 0
HSCF (Horizontal SCale Fraction)
Sets fraction part of horizontal enlargement/reduction ratio
Note :
Simultaneous upscaling and downscaling is not possible (eg HSCALE=0x1000,VSCALE=0x0600).
No scaling (HSCALE=0x0800, VSCALE=0x800) is the default setting.

This register indicates the ITU-RBT656 SAV and EAV status.
To detect error codes, s et NTSC/PAL in the VS bit of VCM. If NTSC is set, reference the number of
data in the capture data count register (CDCN). If PAL is set, reference the number of data in the
capture data counter register (CDCP). If the reference data does not match the stream data , or
undefined Fourth word of SAV/EAV codes are detected, bits 4 to 0 of the video capture status
register (VCS) will be values as follows.
Bits 4-0 CE (Capture Error)
Indicates error occurred during video capture
