24. Usage Notes
• If an A/D conversion in progress is forcibly aborted by setting the ADST bit in the AD0CON0 register to 0
(A/D conversion stops), the A/D conversion result will be incorrect. The AD0i register which is not
performing A/D conversion may also be incorrect. If the ADST bit is set to 0 during A/D conversion, do not
use values obtained from any of AD0i registers.
• External triggers cannot be used in DMAC operating mode. Do not read the AD00 register using instructions.
• Do not perform A/D conversion in wait mode.
• To abort an A/D conversion in progress by setting the ADST bit in the AD0CON0 register to 0 in single sweep
mode, disable interrupts before setting the ADST bit to 0.
