Section 17 A/D Converter

The A/D converter has the following registers.

• 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 data register E (ADDRE)

• A/D data register F (ADDRF)

• A/D data register G (ADDRG)

• A/D data register H (ADDRH)

• A/D control/status register (ADCSR)

• A/D control register (ADCR)

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 17.2.

The converted 10-bit data is stored to 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 is 16-bit width. The data can be read

directly from the CPU.
