Section 15 A/D Converter
15.3
The A/D converter has the following registers. For details on the module stop control register, see
section 22.1.2, Module Stop Control Registers A to C (MSTPCRA to MSTPCRC).
• A/D data register A (ADDRA)
• A/D data register B (ADDRB)
• A/D data register C (ADDRC)
• A/D data register D (ADDRD)
• A/D control/status register (ADCSR)
• A/D control register (ADCR)
15.3.1
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 15.2.
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. Therefore,
when reading ADDR, read only the upper byte, or read in word unit.
