arc_exception priority manipulation #181

Open vandit86 opened 5 days ago

vandit86 commented 5 days ago

``Hello, Can anyone explain why some getter/setter functions in arc_excaption.c, for example int_pri_set(), int_ipm_set(), int_ipm_get().., change the interrupt value passed into the function by adding or subtracting INT_PRI_MIN .. ?????

example : 

int32_t int_ipm_get(void)
{
    return ((int32_t)arc_int_ipm_get() + INT_PRI_MIN);
}

@vandit86 good question, we'll look into that and will get back to you with comments.
