Bit 7 – RUNSTDBY: Run in Standby

Run in Standby

This bit controls whether the ADC will run in Standby sleep mode or not.

ValueDescription
0 The ADC will not run in Standby sleep mode. An ongoing conversion will finish before the ADC enters sleep mode.
1 The ADC will run in Standby sleep mode. The main clock will be requested when the ADC is triggered to perform a conversion.

Bit 5 – LOWLAT: Low Latency

Low Latency

This bit controls whether the analog modules required by the ADC are enabled continuously or only when needed.

ValueDescription
0 The ADC enables the required analog modules only when starting a conversion. This reduces the overall power consumption of the ADC and increases the initialization time when starting an ADC conversion.
1 The analog modules stay enabled when selected as input to the ADC. Using this setting will minimize the initialization time of the ADC.
Note: LOWLAT does not keep the clock source enabled when the ADC is not converting, so a clock startup delay may be experienced even though LOWLAT is set. To avoid such a delay, make sure that the clock source is always enabled.

Bit 0 – ENABLE: ADC Enable

ADC Enable

This bit controls whether the ADC is enabled or not.

ValueDescription
0 The ADC is disabled
1 The ADC is enabled
