USER’S MANUAL
0
The status register (SR) contains condition codes, an interrupt priority mask, and three
control bits. The condition codes are contained in the condition code register (CCR),
the lower byte of the SR. (The lower and upper bytes of the status register are also
referred to as the user and system bytes, respectively.) At the user privilege level, only
the CCR is available. At the supervisor level, software can access the full status reg-
ister.
The priority value in this field (0 to 7) is used to mask interrupts.
Used in multiple-precision arithmetic operations. In many instructions it is set to the
same value as the C bit.
Set when the MSB of a result register is set.
Set when all bits of a result register are zero.
Set when two's complement overflow occurs as the result of an operation.
Set when a carry or borrow occurs during an arithmetic operation. Also used during
shift and rotate instructions to facilitate multiple word operations.
Table D-2 is the SIM address map. The column labeled “Access” indicates the privi-
lege level at which the CPU must be operating to access the register. A designation of
“S” indicates that supervisor access is required. A designation of “S/U” indicates that
the register can be programmed to the desired privilege level.
RESET:
T[1:0]
00 = No tracing
01 = Trace on change of flow
10 = Trace on instruction execution
11 = Undefined; reserved
0 = CPU operates at user privilege level
1 = CPU operates at supervisor privilege level
