bit7
Notes:
• The analog input pins serve as a general-purpose I/O port of the port 5.To use the pin as an
analog input pin, set the port-5 direction register (DDR5) and analog input enable register
(ADER) to switch it to an analog input pin.
• When using the pin as an analog input pin, write 0 to the bit in the port 5 direction register
(DDR5) corresponding to the pin to be used and turn off the output transistor.Also write
"1" to the bit in the analog input enable register (ADER) corresponding to the pin to be
used and set the pin to analog input.
