Analog-to-Digital Converter (ADC10) Module
3.1 Introduction
This section describes the 10-bit successive approximation analog-to-digital converter (ADC10).
The ADC10 module shares its pins with general-purpose input/output (I/O) port pins. See
port location of these shared pins. The ADC10 on this MCU uses V
pins. This MCU uses BUSCLKX4 as its alternate clock source for the ADC. This MCU does not have a
hardware conversion trigger.
3.2 Features
Features of the ADC10 module include:
3.3 Functional Description
The ADC10 uses successive approximation to convert the input sample taken from ADVIN to a digital
representation. The approximation is taken and then rounded to the nearest 10- or 8-bit value to provide
greater accuracy and to provide a more robust mechanism for achieving the ideal code-transition voltage.
Figure 3-2
For proper conversion, the voltage on ADVIN must fall between V
or exceeds V
a 8-bit representation. If ADVIN is equal to or less than V
