Channel configuration registers (addr 0x0E - 0x10)

Tone control bypass

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

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 combination) are bypassed for that channel.

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 volume setting, the master volume setting has no effect on that

channel.
