Text: 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.
