Preliminary

In Level mode, if INT is activated, it will be de-activated when interrupt status registers are read.

In Pulse mode, interrupt will be activated again unless all enabled interrupt status registers are read.

8.3.3 GPI interrupt status

Once a transition occurs at GPI input pins, interrupt status registers(CR10, CR11) will be set. At

the mean time, if interrupt function is enable, INT pin will generate a interrupt. Reading these interrupt

registers will clear themselves and reset interrupt. If an interrupt occurs but no read to interrupt status

registers, interrupt will not be generated again.
