Can please tell me what will happen when interrupt occurs in 8051??
I have gone through books but still i am not clear in the following..
1. Will INT disable all inerrupts before jumping to ISR
2. Do we need to PUSH the contents of register?
3.Difference between RET and reti
4. Do we need to clear the flag before RETI in all cases? (i.e Serial INT/ TIMER/ EXT INT?
I will be hapy if anybody help me in knowing sequence of events occurs as soon as interrupt occurs in 8051
clarifying what Jay say above: AT THE SAME PRIORITY LEVEL refer to "priority as defined in the IP SFR". the 'other priority' that you see in the datasheet only apply if interrupts happen at the exact same time.
