setting can be
Mode where
Initial value
“1” is set in a segment where tone is detected by TONE_RXDET0. “0” is set for any other segments.
0: Not detected
1: Detected
“1” is set in a segment where tone is detected by TONE_TXDET0. “0” is set for any other segments.
0: Not detected
1: Detected
“1” is set in a segment where dial pulse is detected by DPDET0. “0” is set for any other segments.
0: Not detected
1: Detected
“1” is set in a segment where the DTMF signal is detected by DTMFDET0. “0” is set for any other segments.
0: Not detected
1: Detected
An valid code is stored in a segment where the DTMF signal is detected (DTMF0_DET = “1”) by DTMFDET0.
When the DTMF signal is not detected (DTMF0_DET = “0”), “0000” is output. Table 4 shows each code.
