Contextual Info: PRELIMINARY APPLICATION NOTE H8/300L PWM Producing DTMF Signal DTMF Introduction Dual Tone Multi-Frequency (DTMF) is generally used for telephony application. In the case when the MCU does not carry a DTMF generator, a software implementation can be achieved by using the Pulse Width Modulation (PWM) module of the MCU.

Contextual Info: DTMF TONE GENERATION USING THE Z8 CCP I n many applications a microprocessor must access phone lines for communications or data exchange. This has traditionally been accomplished by adding a DTMF tone encoder and a 3.58 MHz crystal; however, the Z8's pulse width modulation capabilities allow DTMF tone generation in software.
