General Description：
TTU983 is a single chip microprocessor for use in TV game. It is composed of CPU(6502),
PPU(picture processor unit), PSG(programmable sound generator), 2K Bytes working RAM,
2K Bytes video RAM, DMA unit, and other control circuit.
Video : TTU983 apply to display variable animated cartoon. In background picture, it supply
2-page size in the screen; In sprite picture, it also supply 64 sprites per frame. Besides,
the X and Y coordinate positions is programmable to display the actual area
AUDIO : TTU983 apply to multi-mix sound output. It with 5 channels programmable sound
generator, include 3 rhythm channels, 1 noise channel, and 1 PCM voice channel.
TTU983 can combine program and video bus into one bus mode. Thus it needs only one
memory IC as the program memory and video memory. Under one bus mode, programmer
specifies the program and video bank individually in the same external memory and then
TTU983 will combine the two independent buses into one bus. External memory can be
extended to 4M bytes through the function decoder of TTU983.
