This section describes the 8-bit analog-to-digital converter (ADC).
Features of the ADC module include:
• Eight channels with multiplexed input
• Linear successive approximation with monotonicity
• 8-bit resolution
• Single or continuous conversion
• Conversion complete flag or conversion complete interrupt
• Selectable ADC clock
The ADC provides eight pins for sampling external sources at pins
PTB7/AD7–PTB0/AD0. An analog multiplexer allows the single ADC
converter to select one of eight ADC channels as ADC voltage in
(V ). V is converted by the successive approximation register-
ADIN ADIN
based analog-to-digital converter. When the conversion is completed,
ADC places the result in the ADC data register and sets a flag or
generates an interrupt.
