If the digital mixer signals an overflow condition by setting the MLOF or MROF bit in the IEC Status Register (Index 6Eh,
Address 0Bh), the controller should correct the error by reducing the digital mixer input volumes in these registers. The
Digital Mixer Input Volume Registers are listed in Table 17.

Digital Mixer Mute. Setting this bit mutes the respective input signal, both left and right inputs.
Left Volume Control. The GL[5:0] bits are used to control the digital mixer left channel input vol-
ume. Each step corresponds to 1 dB gain adjustment. The total range is 0 dB to -63 dB gain.
Right Volume Control. The GR[4:0] bits are used to control the digital mixer right channel input
volume. Each step corresponds to 1 dB gain adjustment. The total range is 0 dB to -63 dB gain.
