The main processing by the program begins with the setting of LED output and switch
input pins. This setting was described in Chapter 3. Next, the program makes the
settings related to the external interrupt and enables the external interrupt. Then, the
program makes LED1 be blinking. Blinking of LED1 continues until the stop or reset
button is pressed on the ACCEMIC screen. When SW1 is pressed after the external
interrupt is enabled, an INT5 interrupt is generated, and an interrupt routine is called.
The interrupt routine clears the interrupt factor and switches LED3 between on and off
states. In summary, this program makes LED1 blinking processing usually as the main
processing, and switches LED3 between the on and off states only when the interrupt is
generated by switch operation.
Set output pins for LED1 and LED3

below. Figure 5.3 shows the flow of the program.
(1) When the program starts, LED1 starts blinking.
(2) When SW1 is pressed, LED3 goes on.
(3) Each time SW1 is pressed, LED3 goes off and on alternately.
