Question 47 (2013):

Submission reference: IN2899

What is the the PIN register?

Answer 47:

For a particular I/O port on the AVR, this is the register that holds the actual values of signals at the pin. E.g. for an input port, this is where you read whether the wire is high (1 or Vdd) or low (0 or Vss). For an output port it generally reflects the value you're driving onto the pin.
