Analog-to-Digital Converter (ADC-15)
Features
Features of the ADC module include:
• 15 Channels with Multiplexed Input
• Linear Successive Approximation
• 8-Bit Resolution
• Single or Continuous Conversion
• Conversion Complete Flag or Conversion Complete Interrupt
• Selectable ADC Clock
Functional Description
Fifteen ADC channels are available for sampling external sources at
pins PTD6/TACLK–PTD0 and PTB7/ATD7–PTB0/ATD0. An analog
multiplexer allows the single ADC converter to select one of 15 ADC
channels as ADC voltage in (ADCVIN). ADCVIN is converted by the
successive approximation register-based counters. When the
conversion is completed, ADC places the result in the ADC data register
and sets a flag or generates an interrupt. See Figure 1.
