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.
Table 58.
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.
Table 59.
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.
