Threshold Setting, resolution = AV /16384 per LSB
DD
This unsigned number sets the threshold point (maximum deviation from the centre value) for the Input
AGC function, where the input gain will be stepped to avoid exceeding the specification limits.
The threshold is set to half of full-scale ($0FFF = VBIAS ± (AV /4)) following a C-BUS Reset or a Power-
DD
Up Reset.
8.2.6 Initialisation of the Program Blocks
Removal of the Signal Processing block from reset (Power Down register, $C0:b5 1→ 0 transition), with
b4 kept low (= 0), will cause all of the Program Blocks (P0 – P4) to be reset to their default values.
