CHAPTER 12 EXTERNAL INTERRUPT CIRCUIT
12.4 Pin
12.4 Pin
This section provides details of the pin of the external interrupt circuit.
■ Pin of External Interrupt Circuit
● INT pin
This pin serves both as an external interrupt input pin and as a general-purpose I/O port.
If the INT pin is set as an input port by the port direction register (DDR) and the corresponding
external interrupt input is enabled by the external interrupt control register (EIC), that pin
functions as an external interrupt input pin (INT).
The state of a pin can always be read from the port data register (PDR) when that pin is set as
an input port. The value of PDR can be read by using the read-modify-write (RMW) type of
instruction.
