Hello everyone,
Was wondering if anyone can explain interupt handler actions in case of enabling interupt with interupt source flag already set.
To be more precise processor - LPC2368, fragment of code;
so in case of action described above will I get interupt executed or do I need to take any extra actions to ensure interupt execution?
tahnk you in advance,
Laurynas.

Code:
*
* *
* * * //U0LSR.5 (THRE) = 1 somewhere before line below
U0IER |= (1 << 1); //Enable TRHE interupts if they were disabled
* * *
* *
*
void uart0_ (void) __irq {
switch (U0IIR & 0x0E) { //swich depending on interupt received
case 0x06:
break;
case 0x04:
break;
case 0x0C:
break;
case 0x02: //<<<<<< will it come here
break;
}
VICVectAddr = 0x00;
}so in case of action described above will I get interupt executed or do I need to take any extra actions to ensure interupt execution?
