6.2.2 INT output
Take Reference Table for INT Output Mode and Polarity Function.
6.2.3 GPI interrupt status
Once a transition occurs at GPI input pins, interrupt status registers (CR07, CR17) will be set. At the
mean time, if interrupt function is enable (CR06, CR16), the INT pin will generate an interrupt
waveform. Reading these interrupt status registers will self clear and reset interrupt. If an interrupt
occurs but never read the interrupt status registers, the interrupt will not be generated again.
*The GPO Pulse Mode output waveform width is 0.5uS.
*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.
*The INT Pulse Mode output waveform width is 0.25uS.
