ANALOGUE MUTE CONTROL
The analogue PGAs can be muted independently and are muted by default. Alternatively, all mute
bits can be set using a master mute bit, MUTE_ALL.
Setting one of these mute bits is equivalent to setting the relevant PGAxx_VOL[7:0] register bits to
mute as defined in Table 22.
Table 25 Analogue Mute Control
PGA ENABLE CONTROL
