1 The two LSBs of the register address, i.e., Bit 1 and Bit 0 in the communication register, specify the channel number of the register being accessed.
2 There is only one mode register, although the mode register can be accessed in one of four address locations. The address used to write the mode register specifies
the ADC channel on which the mode will be applied. Only address 38h must be used for reading from the mode register.
