IRQ5F 0
R/W Indicates the status of an IRQ5 interrupt request.
• When level detection mode is selected
0: An IRQ5 interrupt has not been detected
[Clearing condition]
Driving pin IRQ5 high
1: An IRQ5 interrupt has been detected
[Setting condition]
Driving pin IRQ5 low
• When edge detection mode is selected
0: An IRQ5 interrupt has not been detected
[Clearing conditions]
 Writing 0 after reading IRQ5F = 1
 Accepting an IRQ5 interrupt
1: An IRQ5 interrupt request has been detected
[Setting condition]
Detecting the specified edge of pin IRQ5
4

1: An IRQ4 interrupt has been detected
[Setting condition]
Driving pin IRQ4 low
• When edge detection mode is selected
0: An IRQ4 interrupt has not been detected
[Clearing conditions]
 Writing 0 after reading IRQ4F = 1
 Accepting an IRQ4 interrupt
