TABLE 61. AGC CONTROL, MEAN/MEDIAN, DELAY, MODE (IWA = *008h) RESET STATE = 0x00000000h (Continued)
LOOP GAIN 2 MEAN/MEDIAN.
1 = AGC settles to mean of the signal if LG2 is selected.
0 = AGC settles to median of the signal.
uP LOOP GAIN SELECT. Set to:
1 = loop gain 2.
0 = loop gain 1.
uP LOOP GAIN CONTROL. Set to:
1 = uP loop gain select.
0 = counter controlled loop gain select.
DISABLE LOOP FILTER UPDATE. Set to:
1 = disable loop filter (holds the last value, the uP can load).
0 = normal AGC operation.
SAMPLED MODE.
1 = continuous forward gain updates.
0 = the forward gain held during the interval count (when loop gain 1 is used). The forward gain is continuously updated after the
interval count (when loop gain 2 is used).
ENABLE DELAY. Set to:
1 = enable delay
0 = no delay
NOTE: Delay must be enabled for Sampled Mode.
RESERVED. Set to 0.
CONTINUOUS UPDATE
µP controls loop gain
CONTIUOUS WITH DELAY
TIMED LOOP GAIN SELECTION

Note: There is a gain in the magnitude computation prior to the threshold compare. The gain versus number of clocks is:

The set point should be programmed to the desired level times the magnitude gain.
