Block Diagram of 8/10-bit A/D Converter Pin
Figure 14.3-1 Block Diagram of AN0 to AN11 Pins
Notes:
•
Set the DDR register bits corresponding to the pins to be used as input ports to "0" and apply pull-
up resistance to the external pins. Also, set the bits corresponding to the AICR register to "0".
•
Set the AICR register bit corresponding to the pin to be used as the analog input pin to "1". When
this is done, the value "0" will be read from the PDR register.
