Notes:
(1) Edge sensitive IRQ pin (IRQE = 1).
(2) Level sensitive IRQ pin (IRQE = 0).
(3) If DLY = 1: t_STOPDELAY = 4064 t_CYC (or 128 t_CYC depending on mask option - MC68HC11PH8 only)
If DLY = 0: t_STOPDELAY = 4 t_CYC
(4) XIRQ with X-bit in CCR = 1.
(5) IRQ (or XIRQ, with X-bit = 0; in this case vector fetch will be $FFF4/5).
(6) SA = STOP address.
