Control Register CR

Bit No.

Name

Description

D3

CPGC

This bit is used to control the ON/OFF of call progress tone transmitting.

"0" : The GPTGO output is OFF and the SG level is output.

"1" : The GPTGO output is ON and CPT is output.

D2

DTTIM

This bit is used to control the detect time of DTMF receiver.

"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.

D1

DOEN

This bit is used to control the call progress tone detector and FX detector.

"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.

D0

MFC

This bit is used to control the ON/OFF of DTMF transmit output.

"0" : The DTGO output is OFF and the SG level is output.

"1" : The DTGO output is ON and the DTMF signal is output.
