; Each interrupt vector uses two addresses in rom, that's what the directive

; DC.W means. It says "reserve a word location (.W) in rom (DC) and code

; the routine's label in those two addresses.

; Yet, when an interrupt occurs, for example from the timerB, timerb's routine

; address (timb_rt) will be loaded in the PC and the program will jump to this

; label if allowed. It will execute this routine and then will go back to the main

; program (see interrupt chapter in the datasheet for a more precise description

; of how to handle interrupts in ST72 micros).
