Analog input enable bits
•
When this bit is "0", analog input is disabled.
•
When this bit is "1", analog input is enabled.
•
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.
(AICR1, AICR2)
bit15 to bit10
Unused bits
•
The read value is indeterminate.
•
Writing to these bits have no effect to operation.
