35 CS mode, 3-wire turbo mode
38 Datasheet "3-wire" mode is what most resembles standard SPI connection which,
41 "CS Mode, 3-Wire Turbo Mode" connection in datasheets.
42 NOTE: The datasheet definition of 3-wire mode for the AD4000 series is NOT the
43 same of standard spi-3wire mode.
44 This is the only connection mode that allows configuration register access but
47 Omit the ``adi,sdi-pin`` property in device tree to select this mode.

65 CS mode, 3-wire, without busy indicator
68 Another wiring configuration supported as "3-wire" mode has the SDI pin
69 hard-wired to digital input/output interface supply (VIO). In this setup, the
71 is not possible. This connection mode saves one wire and works with any SPI
74 Set the ``adi,sdi-pin`` device tree property to ``"high"`` to select this mode.

110 In datasheet "4-wire" mode, the controller CS line is connected to the ADC SDI
