pio edge capture

[Altera_Forum]

asume a pio configered to input only, 32 bits,and cupture data on both rising and falling edge. 

does it mean thate data will be cuptured into pio in any change with the input?

The capture function can optionally generate an interrupt in response to the edge event. 

But nothing changes in the basic PIO operation: data is continuously updated in PIO, namely you can get PIO input status whenever you want, by reading the data register.
