DTMF Generator
The DTMF (Dual Tone Multiple-Frequency) signal generator is implemented in the telephone controller. It can generate
16 dual tones and 8 single tones from the DTMF pin. This generator also supports power down, tone on/off function.
The DTMF generator clock source is 3.58MHz, before using this function, the system operation mode must be at Nor-
mal mode.
The power down mode (D_PWDN=1) will terminate all the DTMF generator function, however, the registers DTMFC
and DTMFD are accessible at this power down mode. The duration of DTMF output should be handled by the software.
DTMFD register value could be changed as desired, the DTMF pin will output the new dual-tone simultaneously.
