7.21.3
Table 25 Extended control registers
Programming via extended addressing is done by first
sending a DATA0 data byte EA (3 bits) which specifies the
addresses of the extended register followed by a DATA0
data byte which specifies the contents of the extended
data register (5 bits). The EA extended addresses and
names of the extended data registers are given in
Table 25.
7.21.3.1
Two 5-bit values to program the channel 1 (MA) and
channel 2 (MB) coefficients in the mixer mode. The range
is from 0 to −∞ dB in steps of 1.5 dB. The default settings
are given in Table 5.

7.21.3.2
A 3-bit value to program eight gain settings of the
microphone amplifier. These settings are valid only when
AGC control is enabled and not in the double differential
mode. The default setting is given in Table 5.
