Direct Drive Voice/Dual Tone Melody Controller

5.6. Dual-Tone Generator

A dual-tone melody generator is included to generate 2-channel music songs with a

pleasant square-wave-like timbre. The pitch range of each tone generator is as wide

as 4 octaves (48 different notes totally). The output of dual-tone generator can be

mixed with the output of voice synthesizer to achieve voice playing with BGM

(background music). Additionally, Sonix provides a numbered-musical-notation

representation to help users compose their songs. Further, a MIDI (1.0) file translator

can convert MIDI files into Sonix format.

5.7. I/O Ports

P1 is a 4-bit input port and P2/P3 are two 4-bit I/O ports. Any bit of P2 and P3 can be

programmed as either input or output port individually. Any valid data transition (HꢁL

or LꢁH) of P1, P2 and P3 can reactivate the chip when the chip is in power-down

mode.
