MC68000/MC68008 Core
The supervisor's programming model includes supplementary registers, including the su-
pervisor stack pointer (SSP) and the status register (SR) as shown in Figure 2-2. The SR
contains the interrupt mask (eight levels available) as well as the following condition codes:
overflow (V), zero (Z), negative (N), carry (C), and extend (X). Additional status bits indicate
that the processor is in trace (T) mode and/or in a supervisor (S) state.
