ATD Power Down — This bit provides on/off control over the ATD10B8C block allowing reduced MCU power
consumption. Because analog electronic is turned off when powered down, the ATD requires a recovery time
period after ADPU bit is enabled.

1 Changes all ATD conversion complete flags to a fast clear sequence. Any access to a result register will cause
ATD Power Down in Wait Mode — When entering Wait Mode this bit provides on/off control over the ATD10B8C
block allowing reduced MCU power. Because analog electronic is turned off when powered down, the ATD
requires a recovery time period after exit from Wait mode.
0 ATD continues to run in Wait mode
1 Halt conversion and power down ATD during Wait mode
External Trigger Level/Edge Control — This bit controls the sensitivity of the external trigger signal. See
Table 8-2
External Trigger Polarity — This bit controls the polarity of the external trigger signal. See
External Trigger Mode Enable — This bit enables the external trigger on ATD channel 7. The external trigger
allows to synchronize sample and ATD conversions processes with external events.
0 Disable external trigger
1 Enable external trigger
