1.4Setting Functions

All functions of the devices (PCM3010, DIR1703, DIT4096) on the DEM-DAI3010 are controlled by DIP switches or header pins on this PCB. Therefore, the DEM-DAI3010 does not require a microcontroller or software to transmit data to internal function-setting registers. For specific information on any device, see the data sheet for that device.
