#180566 - it was me,
Responding to: ???'s previous message
I did not think that this is homework, and this "scoring type" seemed to me most suitable ,because
- OP did not specified micro and register
- in 8051 its not defined "interrupt flag register"

As Valentin pointed - Atmel shows some info,
here Philips show different viewpoint (see fig.19, page 14)

And ...
"
If the interrupt was level-activated, then the
external requesting source is what controls the request flag, rather
than the on-chip hardware"
this is from
http://www.nxp.com/acrobat_download2/various/80C51_FAM_HARDWARE_1.pdf

Finally i would try on my micro what exactly happens.
Did You read or tryed , Jan?
