6. DAC interface
OPL3-SA3 supports two types of DAC interface format. One is the conventional DAC interface format
(very common for the consumer audio product) for OPL4-ML/ML2. Another is the I
2S format for
Zoomed Video port. These two types of the formats are shown in the following Fig.6-1, 2.
7. 3D Enhanced Control
OPL3-SA3 integrates the 3D enhanced controller including all the analog components in conventional
systems. Wide, bass, and treble controls are available via SA3 control register, index 14h, 15h, 16h.
One of the four 3D Enhancement modes can be selected according to the frequency response of the
speaker. These are controlled by SA3 control register, index 02h D5, D4 bit (YMODE1-0).
