The ADC provides six pins for sampling external sources at pins
PTA4/ADC0–PTA7/ADC3 and PTB6/ADC4–PTB7/ADC5. An analog
multiplexer allows the single ADC converter to select one of ten ADC
channels as ADC voltage in (V
successive approximation register-based analog-to-digital converter.
When the conversion is completed, ADC places the result in the ADC
data register, high and low byte (ADRH and ADRL), and sets a flag or
generates an interrupt.
Figure 16-2
PTA4–PTA7 and PTB6–PTB7 are general-purpose I/O pins that are
shared with the ADC channels. The channel select bits, ADCH[4:0],
define which ADC channel/port pin will be used as the input signal. The
ADC overrides the port I/O logic by forcing that pin as input to the ADC.
The remaining ADC channels/port pins are controlled by the port I/O
