50 CS mode, 3-wire turbo mode
53 Datasheet "3-wire" mode is what most resembles standard SPI connection which,
55 pin and other SPI lines as usual. This configuration is (misleadingly) called
56 "CS Mode, 3-Wire Turbo Mode" connection in datasheets.
57 NOTE: The datasheet definition of 3-wire mode for the AD4000 series is NOT the
58 same of standard spi-3wire mode.
