DTMF/MELODY GENERATOR
7.1
Introduction
The DTMF/melody generator (DMG) is a multi-functional tone generator built into the
MC68HC05F4 MCU which supports DTMF dialling, melody-on-hold and pacier tone functions.
7.1.1
Features
4 row and 4 column frequencies for DTMF dialling
24 row and 24 column frequencies for dual tone melody
28 frequencies for pacier tone to acknowledge button pressed for pulse dialling
Power saving mechanism for output disable condition
3.579MHz/2 operation
6-bit D/A converter and 28 time steps for sine wave generation
Sine wave or square wave selectable output for melody (or DTMF)
Single or dual tone capability for melody (or DTMF)
