# Starting a Conversion

To enable the ADC module, the ON bit must be set to ‘1’. A conversion may be started by any of the following:

• Software setting the GO bit to ‘1
• An external trigger (source selected by ADACT)
• A Continuous-mode retrigger (see the Continuous Sampling Mode section for more details)
Important: The GO bit must not be set in the same instruction that turns on the ADC. Refer to the ADC Conversion Procedure (Basic Mode) section for more details.
