7.16.3

Extended attack rate

The attack rate shown in Table 148 can be extended to provide up to an 8 dB/ms attack rate

on both limiters.

7.16.4

Extended BIQUAD selector

Bass and treble controls can be configured as user-defined filters when the equalization

coefficients link is activated (BQL = 1) and the corresponding BQx bit is set to 1.

Table 159.

Extended biquad selector, biquad 5

Table 160.

Extended biquad selector, biquad 6

Table 161.

Extended biquad selector, biquad 7

When filters from the 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 given in Table 154.

Note:

BQx bits are ignored if BQL = 0 or if DEMP = 1 (relevant for BQ5) or CxTCB = 1 (relevant for

BQ6 and BQ7).
