13.3.1
ADDRs are 16-bit read-only registers. The conversion result for each analog input channel is
stored in ADDR with the corresponding number. (For example, the conversion result of AN4 is
stored in ADDR4.)
The converted 10-bit data is stored in bits 6 to 15. The lower 6 bits are always read as 0.
The data bus between the CPU and the A/D converter is 16 bits wide. When reading from ADDR,
access must be performed in words. The initial value of ADDR is H'0000.
