Section 18 A/D Converter
18.3
The A/D converter has the following registers.
18.3.1
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 analog input
channel, are shown in table 18.2.
The converted 10-bit data is stored in bits 15 to 6. The lower 6 bits are always read as 0.
The data bus width between the CPU and the A/D converter is 8 bits. 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.
Therefore, byte access to ADDR should be done by reading the upper byte first then the lower
one. Word access is also possible. ADDR is initialized to H'0000.
