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.
Six basic data types are supported:
Addressing in the CPU32 is register-oriented. Most instructions allow the results of the specified oper-
ation to be placed either in a register or directly in memory. This flexibility eliminates the need for extra
instructions to store register contents in memory. The CPU32 supports seven basic addressing modes:
Included in the register indirect addressing modes are the capabilities to post-increment, predecrement,
and offset. The program counter relative mode also has index and offset capabilities. In addition to
these addressing modes, many instructions implicitly specify the use of the status register, stack point-
er, or program counter.
