The status register (see Figure 5) contains the interrupt priority mask (three bits) as well as the following
condition codes: extend (X), negate (N), zero (Z), overflow (V), and carry (C). Additional control bits
indicate that the controller is in the trace mode (T1 or T0), supervisor/user state (S), and master/interrupt
state (M).
