Table 4-33. AGC Decrement Speed
Subaddress 2Bh
Default 04h
7 6 5 4 3 2 1 0
Reserved 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.
111 7 (slowest)
110 6 (default)
000 0 (fastest)
Table 4-34. AGC Decrement Delay
Subaddress 2Ch
Default 00h
7 6 5 4 3 2 1 0
AGC decrement delay [7:0]
AGC decrement delay [7:0]
Number of frames to delay gain decrements.
NOTE: This register affects the decrement delay only when the amplitude reference used by the AGC is either the composite peak
or the luma peak.
Also see AGC increment delay at subaddress 2Ah.
