Hi all, 
i am new to embedded system and hope someone can solve my doubts.
i am reading this example that i have and i came across these.
 
1) T0MR0 = 59999; // 1mSec = 60000 - 1 counts
 
Where does this '60000' come from?
 
2) VICVectCntl0 = 0x20 | 4; 
 
What does '0x20 | 4' mean? 
 
I am very confused of all these values. Hope to hear from someone soon!
