8.3.2 INT output
Two output modes for INT pin. One is LEVEL mode and the other is PULSE.
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
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.
