Serial input data

DSP Serial data input pin (Pulldown)

I Compatible with MSB first/LSB first 24, 20 and 16 bits

Master clock input pin

System clock

I Connect a crystal oscillator between this pin and the XTO pin, or input the

external CMOS clock signal XTI pin. The clock frequency

can be selected by the CKS0 and CKS1 pins.

Crystal oscillator output pin

O When a crystal oscillator is used, connect it between the XTI pin and this pin.

When the external clock is used, keep this pin open.
