19.3.1
The four A/D data registers (ADDRA to ADDRD) are 16-bit read-only registers that store the
results of A/D conversion.
An A/D conversion produces 10-bit data, which is transferred for storage into the A/D data
register corresponding to the selected channel. The upper 8 bits of the result are stored in the upper
byte (bits 15 to 8) of the A/D data register. The lower 2 bits are stored in the lower byte (bits 7 and
6). Bits 5 to 0 of an A/D data register are reserved bits that always read 0. For the reading of the
data, see section 19.4, Bus Master Interface, and section 19.9.3, Access Size and Read Data. Table
19.2 indicates the pairings of analog input channels and A/D data registers.
