I want to know how much time external interrupt need to change from disable(should never occur interrupt) to enable(to occur interrupt again) or vice versa.
I am using following method to enable and disable
PORTA_PCR13 ^= 10U<<16 //for disable
PORTA_PCR13 |= 10U<<16 //for enable
when I disable it and again enable it, sometimes it takes more time(I could not measure it) to occur interrupt again.
whether somebody know whether we need to wait for some time after enable and disable external interrupt?
Please let me know.
Thanks and regards,
