AGC decrement speed [2:0]
AGC decrement speed
Controls the filter coefficient of the first-order recursive automatic gain control (AGC) algorithm when decrementing the gain.
NOTE: This register affects the decrement speed only when the amplitude reference used by the AGC is either the composite peak
or the luma peak.
Also see AGC increment speed at subaddress 29h.
