interrupt handling in am1806.

Hi

         I am planning to use interrupt based key pad driver. In am1806 data sheet i found that we have 8 external interrupt sources. but all these interrupts are mapped to 8 GPIO parts of processor. For example interrupt no 49 can be assigned to GPIO port 7. My doubt is, all the GPIO pins of port(7) can rise the system interrupt (49) or not.

System Interrupt               interrupt name                    source

           49                              GPIO_B7INT                     GPIO Bank 7 Interrupt

   I got the above details from the am1806.pdf. my intension is to rise the same system interrupt(49) for change in state of any GPIO which belongs to port(7). is it possible..? 

Thank you
