Table 4-3. IO_CONFIG Bits 15:0 (Index 0x0001)
Input Configuration (IO_CONFIG Bits 15:0) Firmware Version
0001 8-ch I²S PCM 1
1.Index 0x0078 of OS Manager is valid only if Bit 21 of Index 0x0001 is set with these input configurations. DAI0.L and DAI0.R should be left unused in
the Audio In block of DSP Composer if Bit 21 of OS Manager Index 0x0001 is set.
