2 byte continuous communications.
SDATA is latched at SCK rising edge.
Insert 16 clocks of SCK while CS is low.
Data is invalid if data transmission is aborted during transmission.
The gain conversion table differs in the CDSIN input mode and the ADCIN input mode.
STBY: Reference voltage generator circuit is in the operating state.
SLP: All circuits are in the sleep state.
This bit is used for the IC testing, and cannot be used by the user.
The use of this address is prohibited.
Circuit current and the frequency characteristic are switched.
Data = 0: 36 MHz guarantee
