Bit 7 – RUNSTDBY Run in Standby
This bit controls whether the ADC will run in Standby sleep mode or not.
| Value | Description |
|---|---|
| 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
This bit controls whether the analog modules required by the ADC are enabled continuously or only when needed.
| Value | Description |
|---|---|
| 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
This bit controls whether the ADC is enabled or not.
| Value | Description |
|---|---|
| 0 | The ADC is disabled |
| 1 | The ADC is enabled |
