MSM7584C  
VOXO  
Transmit VOX function signal output.  
VOX function is used to recognize the presence or absence of the transmit voice signal by  
detecting the signal energy. "1" and "0" levels on this pin correspond to the presence and the  
absence, respectively. This result also appears at the register CR7 - B7. The signal energy detect  
threshold is set by the control register data CR6 - B6, B5.  
VOXI  
Signal input for receive VOX function.  
The "1" level on VOXI indicates the presence of voice signal, in which case the decoder block  
processes normal receive signal and the voice signal appears at analog output pins. The "0" level  
indicatestheabsenceofvoicesignal, inwhichcasethebackgroundnoisegeneratedinthisdevice  
is transferred to the analog output pins. The background noise amplitude is set by the control  
register CR6. Because this signal is ORed with the register data CR6 - B3, the control register data  
CR6 - B3 should be set to digital "0".
