interruptcause
flagregister
(pINT_FP815)
Each bit in this register is a cause-of-interrupt flag to indicate the interrupt cause occurrence status. The flag that
has been set can be reset by writing. (Default: indeterminate)
1 (R):
Cause of interrupt has occurred
0 (R):
No cause of interrupt has occurred
When written using the reset-only method (default)
1 (W):
Flag is reset
0 (W):
Has no effect
When written using the read/write method
1 (W):
Flag is set
0 (W):
Flag is reset
See “Key Input, Port Input 0–3 Interrupt Cause Flag Register (0x300280)” for more information.
