Good evening, hope everyone is safe out there. I am trying to initialize the external interrupt for the falling edge for pin 0 to 7 in HIFIVE revB. When I push the push button the external interrupt handler is executed. however, it is stuck in the handler even though I wrote back to the claim_commplite register. Also, to break out of the loop I cleared bit number 11 in mie register. however, when I enabled the mie later in main(), CPU started to execute the external_interrupt even without pushing the push button. If any one could spot what I am missing, I will be so gratfull.
