reserved, not used

DISPC

Disable Phase Correction. If DISPC = 1, phase correction is disabled.

CDC2TM2

Functional test modes of Codec 2. These 3 bits select the functional test modes of

Codec 2; see Table 7.

CDC2TM1

CDC2TM0

CDC1TM2

Functional test modes of Codec 1. These 3 bits select the functional test modes of

Codec 1; see Table 7.

CDC1TM1

CDC1TM0

HFMICON

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).

HSMICON

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).

LHFEN

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.

EHSEN

Earpiece Enable for Handset. This bit enables the Noise Shaper data to the DAC in

Codec 2.

CDC2ON

Codec 2 ON. When CDC2ON = 1, Codec 2 is ON.

ADD_DAC

Add a DC offset in the microphone ampliﬁer of Codec 1.

LIF1_EN

Line Interface Enable for Codec 1. This bit enables the Noise Shaper data to the DAC

in Codec 1.

CDC1ON

Codec 1 ON. When CDC1ON = 1, Codec 1 is ON.
