16.2
Table 16.1 summarizes the input pins used by the A/D converter.
Table 16.1 Pin Configuration
16.3
The A/D converter has the following registers.
16.3.1
There are four 16-bit read-only ADDR registers; ADDRA to ADDRD, used to store the results of
A/D conversion. The ADDR registers, which store a conversion result for each channel, are shown
in table 16.2.
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 8 bits wide. The upper byte can be read
directly from the CPU, however the lower byte should be read via a temporary register. The
temporary register contents are transferred from the ADDR when the upper byte data is read.
