Underlined pin names and descriptions apply when the device is configured without a serial port interface, referred to as No SPI mode.
Some pin descriptions depend on whether a serial port is used (SPI mode) or not (No SPI mode), indicated by the labels SPI and No SPI.
Some pin descriptions depend on the interface configuration: full-duplex (FD), half-duplex interleaved data (HD12), half-duplex parallel data (HD24), and a half-duplex
interface similar to the AD9860 and AD9862 data interface called clone mode (Clone). Clone mode requires a serial port interface.
