Figure 13 Supervisor Programming Model Supplement
4.3 Status Register
The status register contains the condition codes that reflect the results of a previous operation and can
be used for conditional instruction execution in a program. The lower byte containing the condition
codes is the only portion of the register available at the user privilege level; it is referenced as the con-
dition code register (CCR) in user programs. At the supervisor privilege level, software can access the
full status register, including the interrupt priority mask and additional control bits.
