GPIO_ISR3 is the interrupt input status register for GPIO[39:37; 32].
Note:
bit
CX82100 Home Network Processor Data Sheet
If an interrupt is level-sensitive, the corresponding status bit will remain a 1 as
long as the interrupt source is not removed. The status bit can be cleared only
after the interrupt source is removed and a 1 is written to the bit.

GPIO[X] Interrupt Status, 39≥ ≥ ≥ ≥ X≥ ≥ ≥ ≥ 32.
Reading:
bit #Y = 0 = > No interrupt detected on GPIO[X].
bit #Y = 1 = > Interrupt input detected on GPIO[X].
Writing:
0 to bit #Y = > no effect
1 to bit #Y = > clear the interrupt on GPIO[X].
Note: If the interrupt is level-sensitive, the status bit will remain a 1 as
long as the interrupt resource is not removed. The bit can be cleared
only after the resource is removed and a 1 is written to it.
