An inverting amplifier inside the chip is connected between 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 OSC2 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.
