Sample Programs for External Interrupt Circuit

We provide sample programs that can be used to operate the external interrupt circuit.
Sample Programs for External Interrupt Circuit
For information about the sample programs for the external interrupt circuit, refer to "
in Preface.
Setup Methods without Sample Program
Detection levels and setup methods
Four detection levels are available: no edge detection, rising edge, falling edge, both edges
The detection level bits (EIC. SL01, SL00 or SL11, SL10) are used.
How to use the external interrupt pin
Set the corresponding data direction register (DDR0, DDRE) to "0".
