7.21.3.3
A 2-bit value to program the mode of the digital mixer.
There are four modes: double differential, input channel 1
select, input channel 2 select and digital mixer mode.
The default setting is given in Table 5.
Table 28 Mixer mode switch settings
7.21.3.4
A 1-bit value to enable the AGC input. The default setting
is given in Table 5.
Table 29 AGC control settings
7.21.3.5

7.21.3.6
A 7-bit value to program the input channel 2 amplifier gain.
The range is from −3 to +60.5 dB in steps of 0.5 dB. These
settings are only valid when AGC control is disabled and
not valid in the double differential mode.

7.21.3.7
A 3-bit value to program the attack and the decay
parameters of the digital AGC. The default setting is given
in Table 5.
