Disable Phase Correction.
If DISPC = 1, phase correction is disabled.
Functional test modes of Codec 2.
These 3 bits select the functional test modes of
Codec 2; see Table 7.
Functional test modes of Codec 1.
These 3 bits select the functional test modes of
Codec 1; see Table 7.
Hands-free Microphone ON in Codec 2.
When this bit is set the internal microphone
reference voltage VREFMIC is connected to pad VMIC_HF (supply pad for the external
hands-free microphone).
Handset Microphone ON in Codec 2.
When this bit is set the internal microphone
reference voltage VREFMIC is connected to pad VMIC_HS (supply pad for the external
handset microphone).
Loudspeaker Enable for hands-free.
This bit enables the Noise Shaper data in
Codec 2 to the hands-free pads EARP_HF and EARM_HF.
Earpiece Enable for Handset.
This bit enables the Noise Shaper data to the DAC in
Codec 2.
Codec 2 ON.
When CDC2ON = 1, Codec 2 is ON.
Add a DC offset in the microphone amplifier of Codec 1.
Line Interface Enable for Codec 1.
This bit enables the Noise Shaper data to the DAC
in Codec 1.
Codec 1 ON.
When CDC1ON = 1, Codec 1 is ON.
