setting can be
Mode where
Initial value
0 : Stop
1 : Operate
Setting this bit to “1” makes TONE_RXDET1 start operating.
0 : Stop
1 : Operate
Setting this bit to “1” makes TONE_TXDET1 start operating.
0 : Stop
1 : Operate
Setting this bit to “1” makes the FSK generator 1 (FSKGEN1) start operating.
Note:
To activate FSKGEN1, be sure to do so with TGEN1 and DPGEN1 placed in a stop state. Using TGEN1,
FSKGEN1 and DPGEN1 simultaneously is not allowed.
0 : Stop
1 : Operate
Setting this bit to “1” makes TD_RXDET1 start operating.
0 : Stop
1 : Operate
Setting this bit to “1” makes TD_TXDET1 start operating.
0 : Stop
1 : Operate
Setting this bit to “1” makes DTMFDET1 start operating.
0 : Stop (The echo canceller will be bypassed.)
1 : Operate
Setting this bit to “1” makes EC1 start operating.
Remarks: At the time of operation start of EC1, the echo canceller's internal coefficients are cleared and then
activated.
Note:
If either TD_RXDET1 or TD_TXDET1 is activated, using TONE_RXDET1 is not allowed, nor is
TONE_TXDET1.
