i see question related pic18 , assembly language. interrupt masking letting interruptions handled or not, depending on want pc or microcontroller under specific circumstances. whenever programme gets interruption, have identify source , execute corresponding interrupt service routine.

the main advantadge of interruptions in relation polling, fact processor not waste clock cycles asking input/output device if ready receive info or if has sent new info treated.
