1. Stereo Mode (SPC1-0 bits = “00”: SW2 = “0”, SW3= “0”, SW4= “0”, SW5= “0”, SW6= “0”)
Table 20 shows the signal status and output condition when SPC1-0 bits= “00”. This output configuration is suitable for
a traditional stereo speaker system. Refer to the Figure 55 for functions and signal paths of the DSP block.
