Function
RW
8 low-order bits in an A/D conversion result
RO
In 10-bit mode: 2 high-order bits in an A/D conversion result
RO
In 8-bit mode: when read, its content is indeterminate.
When read, its content is indeterminate.

NOTES:
1. In DMAC operating mode, register value read by program is indeterminate.
2. Register value is indeterminate when written while the A/D conversion is stopped.
3. Register value is indeterminate if the next A/D conversion result is stored before reading the register.
4. The AD00 register is available in DMAC operating mode. Other registers are indeterminate.
5. In DMAC operating mode and 10-bit mode, set DMAC for a 16-bit transfer.
