The MAX11335–MAX11340 communicate between the
internal registers and the external circuitry through the
SPI-/QSPI-compatible serial interface.
register access and control.
detail the various functions and configurations.
For ADC mode control, set bit 15 of the register code
identification to zero. The ADC Mode Control register
determines when and under what scan condition the
ADC operates.
To set the ADC data configuration, set the bit 15 of the
register code identification to one.
The MAX11335–MAX11340 feature three power-down
modes.
The devices shut down when the SPM bits in the ADC
Configuration register are asserted

All circuitry is fully powered up at all times.
The device enters full shutdown mode at the end of each conversion. All circuitry
is powered down. The device powers up following the falling edge of CS. It takes 2
cycles before valid conversions take place. The information in the registers is retained.
