This bit is used to control the ON/OFF of call progress tone transmitting.
This bit is used to control the detect time of DTMF receiver.
This bit is used to control the call progress tone detector and FX detector.
This bit is used to control the ON/OFF of DTMF transmit output.
"0" : The GPTGO output is OFF and the SG level is output.
"1" : The GPTGO output is ON and CPT is output.
"0" : Normal detect "1" : High-speed detect
When there is enough time, set to the normal detect mode (DTTIM = "0") because the
high-speed detect mode sometimes causes erroneous detection by noise or voice signal.
"0" : The CPDO and FXDO output pins and CPDR and FXDR registers are fixed to "0".
"1" : The CPDO and FXDO output pins and CPDR and FXDR registers become valid.
"0" : The DTGO output is OFF and the SG level is output.
"1" : The DTGO output is ON and the DTMF signal is output.
