-M2TX1 : Reset value : 0. Setting this bit to 1 will
enable the mono codec #2 DAC output
to the HandTx1 output Pin. Setting the
bit to 0 will mute the signal.
-M2TX2 : Reset value : 0. Setting this bit to 1 will
enable the mono codec #2 DAC output
to the HandTx2 output Pin. Setting the
bit to 0 will mute the signal.
-M2TX3 : Reset value : 0. Setting this bit to 1 will
enable the mono codec #2 DAC output
to the HandTx3 output Pin. Setting the
bit to 0 will mute the signal.
M2TXG : Reset value : 0. Setting this bit to 1 will
place a -6dB attenuator in the output
DAC path. Setting thisbit to0 willresult
in a gainpath of 0dB.

+LOOPR : Resetvalue :0.Settingthisbitto1will
loop the ADC digital data to the DAC
converter on the audio codec right
converter. Setting this bit to 0 will
cause the DAC converter to receive
its digital data from the serial port
whichis normaloperation.
+LOOPL
: Reset value : 0. Setting this bit to 1
will loop the ADC digital data to the
DACconverterontheaudiocodecleft
converter. Setting this bit to 0 will
cause the DAC converter to receive
its digital data from the serial port
whichis normaloperation.
+LOOPM1: Reset value : 0. Setting this bit to 1
will loop the ADC digital data to the
DAC converteron themonocodec#1
converter. Setting this bit to 0 will
cause the DAC converter to receive
its digital data from the serial port
which is normal operation.
+LOOPM2: Reset value : 0. Setting this bit to 1
will loop the ADC digital data to the
DAC converteron themonocodec#2
converter. Setting this bit to 0 will
cause the DAC converter to receive
its digital data from the serial port
which is normal operation.
