Alternatively, an external (CMOScompatible) clock (powered relative to VD+) can be supplied into the OSC2 pin to provide themaster clock for the device.Control Pins and Serial Data I/OCS - Chip Select.When active low, the port will recognize SCLK. When high the SDO pin will output a highimpedance state. CS should be changed when SCLK = 0.46 DS289PP5
