EQ_EN

0 : EQ ON

1 : EQ OFF (bypass BQ 0-7 of channels 1 and 2)

0x00

B_MAP

0 : Ignore bank-mapping in bits D31–D8.Use default

mapping.

1 : Use bank-mapping in bits D31–D8

BQL

0 : L and R can be written independently

1 : L and R are ganged for EQ biquads; a write to left-channel

BQ is also written to right-channel BQ. (0x29–0x2F is

ganged to 0x30–0x36. Also 0x58–0x5B is ganged to

0x5C–0x5F)

2:0

BAND_SW

[2:0]

000 : No bank switching. All updates to DAP

001 : Configure bank 1 (32kHz by default)

010 : Configure bank 2 (44.1/48kHz by default)

011 : Configure bank 3 (other sample rates by default)

100 : Automatic bank selection
