Table 21 shows the possible mixing configurations of
the analog audio output mixer. The sidetone, line 1, and
line 2 signals can be routed to either the left or right
audio output in the combinations shown in Table 21.
The left DAC output is only available on the left audio
output and similarly for the right DAC output.

Programmable-Gain Adjustment for Digital Audio
Inputs (PGADS1/PGADS2)
PGADS1/PGADS2 configures the gain adjustment for the
digital audio interface inputs. Code 0x00 is full signal
while 0xFF is full attenuation. This programmable-gain
adjustment follows the mono mixers. Table 23 shows
simplified gain control settings for digital signal inputs.
X = Don’t care.
