Table 79.
Table 80.
Table 81.
When filters from 5th to 7th are configured as user-programmable, the corresponding
coefficients are stored respectively in addresses 0x20-0x24 (BQ5), 0x25-0x29 (BQ6), 0x2A-
0x2E (BQ7) as in
BQx bits are ignored if BQL = 0 or if DEMP = 1 (relevant for BQ5) or CxTCB = 1 (relevant for
BQ6 and BQ7).
Soft volume configuration registers (addr 0x37 - 0x38)
Soft volume update has a fixed rate by default. Using register 0x37 and 0x38 it is possible to
override the default behavior allowing different volume change rates.
It is also possible to independently define the fade-in (volume is increased) and fade-out
(volume is decreased) rates according to the desired behavior.
