Complete register map derived from TI ADS79xx datasheet SLAS605C. The ADS7952 uses 16-bit full-duplex SPI frames:

  • DI[15:12] mode select, DI[11] program enable, DI[10:7] channel/reset, DI[6] range, DI[5] power-down, DI[4] data descriptor, DI[3:0] GPIO
  • DO[15:12] channel address, DO[11:0] 12-bit ADC data
