ADC1 converter (continued)
The ADC1 module allows complete freedom in design of the sources for the analog inputs. The period of the
sample time is user-defined so that the high-impedance can be accommodated without penalty to the
low-impedance sources. The sample period begins when the SAMPLE START bit of the ADC1 control register
(ADCTL.6) is set to 1. The end of the signal sample period occurs when the conversion bit (CONVERT START,
ADCTL.7) is set to 1. After a hold time, the converter will reset the SAMPLE START and CONVERT START bits,
signaling that a conversion has started and that the analog signal can be removed.
