Description:

This offsets the vertical scale from its nominal value. A positive number stretches the image and a

negative number compresses the image.

If the value written to VSS is beyond the internally calculated limit, the maximum (or minimum in case of a

negative number) will be written back to the VSS register. An external processor can then read VSS to

determine if the last value written to VSS was beyond the limit.

NOTE: It can take up to 25ms for the internal micro-controller calculates the limits for HPO, VPO, HSS,

VSS, HPP, and VPP. These registers should not be read until 10ms after writing to any of these registers.

Range:

{-32768 : +32767} 2’s Complement

Reset Value:

0x0000
