NEGATIVE ANALOG POWER
A gate inside the chip is connected to these pins and can be used with a crystal to provide the
master clock for the device. Alternatively, an external (CMOS compatible) clock (powered
relative to VD+) can be supplied into the XIN pin to provide the master clock for the device.
When active low, the port will recognize SCLK. When high the SDO pin will output a high
impedance state. CS should be changed when SCLK = 0.
SDI is the input pin of the serial input port. Data will be input at a rate determined by SCLK.
A clock signal on this pin determines the input/output rate of the data for the SDI/SDO pins
respectively. This input is a Schmitt trigger to allow for slow rise time signals. The SCLK pin
will recognize clocks only when CS is low.
POSITIVE ANALOG POWER
SDO is the serial data output. It will output a high impedance state if CS = 1.
