1. INTRODUCTION
SNC745 is a 64mins two-channel speech/melody and 4-channel wave-table melody
voice chip. It based on reduced 16-bit fixed-point DSP architecture. SNC745 provides
user some necessary and efficient DSP instructions. Furthermore, SNC745 provide one
10-bit PWM and one 10-bit DA converter to driving speaker for speech/melody output.
User can select PWM or DA by programming DA/PWM control register, and only one
function can be active at the same time.
