5.9.4 Tone Control Bypass

Tone control(bass/treble) can be bypassed on a per channel basis for channels 1 and 2.

CxTCB:

0 - Perform Tone Control on Channel X - normal operation

1 - Bypass Tone Control on Channel X

5.9.5 EQ Bypass

EQ control can be bypassed on a per channel basis for channels 1 and 2. If EQ control is bypassed on a

given channel the prescale and all filters (high-pass, biquads, de-emphasis, bass, treble in any combina-

tion) are bypassed for that channel.

CxEQBP:

0 - Perform EQ on Channel X - normal operation

1 - Bypass EQ on Channel X

5.9.6 Volume Bypass

Each channel contains an individual channel volume bypass. If a particular channel has volume bypassed

via the CxVBP = 1 register then only the channel volume setting for that particular channel affects the vol-

ume setting, the master volume setting will not affect that channel.

5.9.7 Binary Output Enable Registers

Each individual channel output can be set to output a binary PWM stream. In this mode output A of a

channel will be considered the positive output and output B is negative inverse.

CxBO:

0 - DDX tri-state output - normal operation

1 - Binary OutputLimiter Select

Limiter Selection can be made on a per-channel basis according to the channel limiter select bits.
