DATA REGISTER
(RS2, RS1, RS0 = 0, 1, 1; Power-On/Reset = 0x000000)
The conversion result from the ADC is stored in this data
register. This is a read-only, 24-bit register. On completion of a
read operation from this register, the RDY pin/bit is set. When
the DAT_STA bit in the mode register is set to 1, the contents of
the status register are appended to each 24-bit conversion. This
is advisable when several analog input channels are enabled
because the three LSBs of the status register (CHD2 to CHD0)
identify the channel from which the conversion originated.
