Table 32 SPKOUT Volume Control
ZERO CROSS TIMEOUT
A zero-cross timeout function is also provided so that if zero cross is enabled on the input or output
PGAs the gain will automatically update after a timeout period if a zero cross has not occurred. This
is enabled by setting SLOWCLKEN. The timeout period is dependent on the clock input to the digital
and is equal to 2
Table 33 Timeout Clock Enable Control
MONO MIXER AND OUTPUT
The MONOOUT pin can drive a 16Ω or 32Ω headphone or a line output or be used as a DC
reference for a headphone output (see Headphone Output section). It can be selected to drive out
any combination of DAC, Bypass (output of input BOOST stage) and MIC2. The Bypass path has
the option of 0dB or -10dB attenuation, selected by the MONOATTN register bit. This output is
enabled by setting bit MONOEN.
