|
The GPIO controller will not report any new GPI interrupt as long as its interrupt status
|
|
register hasn't been read.
|
|
Reading the interrupt status register happens on a falling edge of the INT pin.
|
|
There seems to be a condition when the GPIO controller detects an interrupt but it's INT
|
|
pin stays high which masks any subsequent interrupts.
|
|
To avoid being stuck in that state, fire a timer to periodically check the interrupt status
|
|
register.
