Section 15 A/D Converter
15.3.1
There are eight 16-bit read-only ADDR registers, ADDRA to ADDRH, used to store the results of
A/D conversion. The ADDR registers, which store a conversion result for each channel, are shown
in table 15.2.
The converted 10-bit data is stored in bits 15 to 6. The lower 6-bit data is always read as 0.
The data bus between the CPU and the A/D converter has a 16-bit width. The data can be read
directly from the CPU. ADDR must not be accessed in 8-bit units and must be accessed in 16-bit
units.
