Ñ 76 Ñ PIN NAME I/O DESCRIPTION Oscillator connection pins. When external clock is used, input clock into XT pin and leave XT pin open. Outputs sampling frequency selected at recording or playback. VCK pin is used as a synchronizing signal when external ADC or DAC is used. When this pin is ÒLÓ level input, the LSI is initialized. Pins for testing. Set the pins to ÒLÓ. Analog circuit signal ground output pin. Inverting input pin for built-in OP amplifier. Noninverting input pin is connected to SG (Signal...
