(9)Timer 5 6 interrupt
An interrupt is generated by an overflow of timer 5 or 6. Their
priorities are same, and can be switched by software.
(10)BRK instruction interrupt
This software interrupt has the least significant priority. It does
not have a corresponding interrupt enable bit, and it is not af-
fected by the interrupt disable flag I (non-maskable).
