32 Devices of the AD4000 series can be connected to the SPI host controller in a
35 CS mode, 3-wire turbo mode
38 Datasheet "3-wire" mode is what most resembles standard SPI connection which,
40 pin and other SPI lines as usual. This configuration is (misleadingly) called
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.
