SCLK – Serial Clock Input/Output, Pin 23

The SMODE pin determines whether the SCLK signal is an input or an output signal. SCLK

determines the rate at which data is clocked out of the SDO pin. If the converter is in SSC

mode, the SCLK frequency will be determined by the master clock frequency of the converter

(either MCLK or the internal oscillator). In SEC mode, the user determines the SCLK frequency.

If SMODE = VL (SSC Mode), SCLK will be in a high-impedance state when CS is high.

RDY – Ready, Pin 24

At the end of any conversion RDY falls to indicate that a conversion word has been placed into

the serial port. RDY will return high after all data bits are shifted out of the serial port or two mas-

ter clock cycles before new data becomes available if the CS pin is inactive (high); or two mas-

ter clock cycles before new data becomes available if the user holds CS low but has not started

reading the data from the converter when in SEC mode.
