TMS 600 SAB-C167 80C167 Microcontroller Support Instruction Manual
Table 2–2: Meaning of special characters in the display
Character or string displayed
Meaning
m
The instruction was manually marked as a program fetch
****
Indicates there is insufficient data available for complete
disassembly of the instruction; the number of asterisks
indicates the width of the data that is unavailable. Each two
asterisks represent one byte.
#
Indicates an immediate value
t
Indicates the number shown is in decimal, such as #12t
In Hardware display format, the disassembler displays certain cycle type labels in
parentheses. Table 2–3 shows these cycle type labels and gives a definition of the
cycle they represent. Reads to interrupt and exception vectors will be labeled
with the vector name.
Table 2–3: Cycle type definitions
