DAC_I2C, DAC_I2Cenable, DAC_I2Cdisable (for SD5.2 only) This nucleus checks the interface between the I2C controller on the ZiVa5 and the external DAC board. DAC_ClockInternal, DAC_ClockExternal (for SD5.2 only) These nuclei select the final clock input to the audio DAC. - Internal clock means the PCM clock from the monoboard is used. - External clock means the DSD clock on the AV board is used. DAC_AudioPreMuteOn, DAC_ AudioPreMuteOff (for SD5.2 only) This nucleus selects Audio Pre-mute on/off. DAC_CentreOn, DAC_ CentreOff (for SD5.2 only) This nucleus selects the centre on/off. BedReadFlashID Loads a special diagnostic firmware on the front engine which reads the Flash device and manufacturer�s ID . BedCalcRomChkSum Loads a special diagnostic firmware on the front engine that calculates the checksum of the front engine ROM. BedScratchTest Loads a special diagnostic firmware on the front engine that checks the scratch detector circuit of the front engine. DAC_Reset This nucleus resets the DAC board. DAC_ModeCDDA, DAC_ModeDVD48, DAC_ModeDVD96, DAC_ModeDSD (for SD5.2 only) - DAC_ModeCDDA switches the DACs into CDDA mode. - DAC_ModeDVD48 switches the DACs into DVD 48 kHz mode. - DAC_ModeDVD96 switches the DACs into DVD 96 kHz mode. - DAC_ModeDSD switches the DACs into DVD DSD mode.
