NOTES:
1. When the AD0CON3 register is rewritten during the A/D conversion, the conversion result is
indeterminate.
2. The AD0CON3 register may be read uncorrectly during the A/D conversion. It must be read or written
after the A/D converter stops operating.
3. When the DUS bit is set to "1", the AD00 register stores all A/D conversion results.
4. When the DUS bit is set to "1", set the DMAC.
5. Refer to the note for the CKS0 bit in the AD0CON0 register.
