A/D conversion result register n for DMA (ADDMAn)
The ADDMAn register is a 16-bit register holding the result of the latest A/D conversion operation,
and is used for DMA transfer of ADCn results into the internal RAM. It has an overrun detection
flag indicating an overrun situation of the DMA transfer mechanism (n = 0, 1).
This register is read-only in 16-bit units.
Reset input causes an undefined register content.
Caution:
Do not read the ADDMAn register by CPU during DMA transfer activities. If this
register is read by CPU, overflow detection cannot be ensured.

Overrun Detection Flag
0
No A/D conversion result overrun was detected.
1
At least one A/D conversion result was overrun since the last read of the
ADDMAn register.
•
The ODFn flag is used for indicating a DMA transfer failure of the A/D conversion
results.
•
The ODFn flag is cleared (0), when the A/D conversion is stopped (ADCEn bit of the
ADMn0 register is cleared to 0).
